For live software demos on Windows, I’d use OBS Studio.

• OBS Studio — best all-around choice. It’s free/open-source, records windows or the whole display, captures your microphone, and on Windows 10/11 can capture audio from individual applications. You can, for example, capture your demo app’s audio while keeping Teams/Slack/notification sounds out. OBS Studio OBS Studio

obsproject.com

• Camtasia — better if you want an integrated record → edit → annotate → export workflow rather than a production/streaming tool. It supports screen, microphone, and system-audio recording. Camtasia
• Windows Snipping Tool/Game Bar — convenient for quick captures, but I’d choose OBS if you're doing polished demos where controlling exactly which app audio is recorded matters.

My recommended OBS setup

For a typical software demo:

1. Add Window Capture for the application you're demonstrating.
2. Enable Capture Audio on that window, or add Application Audio Capture as a separate source. OBS Studio
3. Add your microphone as an Audio Input Capture source.
4. Disable global Desktop Audio if you're using application-specific audio, to avoid recording the same sound twice/creating an echo. OBS Studio
5. Record to MKV, then let OBS remux it to MP4 afterward if you need MP4 for editing/uploading.

The particularly useful part is that OBS can give you separate audio sources/tracks, so your narration and application audio can be adjusted independently afterward. OBS Studio

If you're doing frequent product/software demos, I'd pick OBS unless you specifically want Camtasia's built-in editing and annotation workflow.

For live software demos on Windows, I’d use OBS Studio. It’s free, very flexible, and particularly well suited to capturing both the application and its audio.

Why OBS is a good fit

• Capture a specific app/window rather than your whole desktop.
• Capture application audio separately — on Windows 10 (2004+) and Windows 11, OBS has an Application Audio Capture source. OBS Studio
• You can record your microphone + app audio independently, which is useful for adjusting your voice and demo audio later.
• You can create scenes for things like:

• Full-screen software demo
• Demo + webcam
• Demo + presentation/slides
• Intro/outro
• It records locally without requiring an internet connection.
• You can produce high-quality MP4/MKV recordings and configure hotkeys for starting/stopping recordings.

A simple setup I'd use

In OBS, create a scene with:

1. Window Capture → your software/demo window.
2. Application Audio Capture → the app producing the sound.
3. Audio Input Capture → your microphone.
4. Optionally Video Capture Device → webcam.

OBS specifically recommends disabling its global Desktop Audio when you're using Application Audio Capture, otherwise you can end up capturing the same audio twice and creating an echo. OBS Studio

If you want all computer audio rather than audio from one particular app, OBS can also capture an audio output device directly. OBS Studio

Other options

Windows Snipping Tool is convenient for very quick recordings, but I'd choose OBS for serious software demos. Snipping Tool can record a selected rectangular area, but its workflow is much less focused on sophisticated audio mixing. Microsoft Support

Xbox Game Bar is another quick option and can include system audio, but it's primarily designed around simple game/app clips rather than polished demo production. Microsoft Support

My recommendation: OBS + Application Audio Capture + a decent microphone. It's probably the best combination if you're making demos that you'll actually publish or send to customers.

If you tell me what kind of demos you're recording (browser apps, desktop software, coding/terminal, games, etc.), I can give you an exact OBS setup and recording settings for clean 1080p/4K video and good audio.

For live software demos on Windows, I’d use OBS Studio. It’s free, reliable, and gives you much better control over system/app audio than most simple screen recorders. OBS Project OBS Project

My recommendation: OBS Studio

obsproject.com

It can capture:

• Your software window or entire desktop
• Audio from specific applications
• Your microphone separately
• Webcam/camera
• Multiple scenes and layouts
• System audio without needing to record it through your microphone

On current Windows versions, OBS supports Application Audio Capture, so you can add an application as its own audio source. You can also capture audio directly alongside Window Capture or Game Capture. OBS Project

A good demo setup would be:

OBS
├── Display/Window Capture → software you're demonstrating
├── Application Audio Capture → software's audio
├── Mic/Aux → your microphone
└── Webcam → optional

This is particularly nice if, for example, you want Chrome/your app audio + your voice, while excluding Slack/Discord/other background sounds.

Easiest alternatives

Xbox Game Bar is the simplest if you just need a quick recording. Windows supports recording an app and including system/app audio, with Win + Alt + R to start/stop. Microsoft Support

Clipchamp is better if you want to record and immediately do basic editing. Microsoft supports screen/window recording and system-audio sharing in its screen-recording workflow, although audio capture has more limitations depending on whether you're recording a browser tab or using the Windows app. Microsoft Support Microsoft Support

Bottom line:

• Professional/live software demos → OBS Studio
• Quick one-off recording → Xbox Game Bar
• Record + simple editing → Clipchamp

If you're doing live demos where you talk over an app's audio, I'd definitely pick OBS.

Lightweight/simple options

• getsharex.com — great free Windows capture tool; better for quick clips than full production demos. Toolradar
• support.xbox.com — built into Windows, good for quick recordings, but limited compared with OBS. TechNewsKB

My recommendation by scenario

A few tips for software demos:

• Use a USB headset or good mic; laptop microphones often pick up keyboard/fan noise.
• In OBS, put mic and system audio on separate tracks so you can rebalance them later.
• Turn off Windows notification sounds before recording.
• Do a 30-second test recording first—system audio routing is the most common thing to miss.

For most Windows software demos, I’d use OBS + a separate editor (like DaVinci Resolve) if needed; if you want an all-in-one “record and polish” workflow, use Camtasia.

For live software demos on Windows where you need the app's system audio captured, I’d use OBS Studio.

Best choice: OBS Studio

obsproject.com is free, open-source, and gives you much more control than Windows' built-in recording tools.

The big advantage for your use case is per-application audio capture. On Windows 10/11, OBS can capture audio from individual apps as separate sources—for example:

• Your demo application → video + its audio
• Chrome → browser audio
• Slack/Teams → optionally capture separately
• Your microphone → separate track
• Webcam → separate video source

OBS specifically supports Application Audio Capture, and you can also enable audio directly on Window Capture/Game Capture sources. OBS Studio

How I'd set up a software-demo recording

In OBS, I'd create:

1. Window Capture — your software demo
2. Application Audio Capture — the demo application's audio
3. Audio Input Capture — your microphone
4. Video Capture Device — webcam, if you want your face visible
5. Optional Display Capture — if you need to move between multiple applications

Then record to MKV and have OBS automatically remux to MP4 afterward.

One particularly useful feature: keep your microphone and application audio on separate tracks. That lets you lower/remove the application's audio later without affecting your narration.

What about Clipchamp?

clipchamp.com is easier if you want something simple and don't need much control. Its screen recorder can include system audio when the recording interface provides the Share system audio option. Microsoft Support Microsoft Support

But there's an important limitation: for personal-account screen recording, Microsoft's documentation says audio sharing is available when recording a browser tab, rather than giving you OBS-style per-application audio routing. Microsoft Support

My recommendation

For professional software demos → OBS Studio.

It's especially worth using if you want:

• 🎙️ Clean narration
• 🔊 App/system audio
• 🖥️ High-quality screen capture
• 🎚️ Independent audio tracks
• 📹 Webcam + screen
• 🔄 Multiple scenes you can switch between live
• 🎬 Recording now and editing later

If you're doing SaaS/product demos, I can also give you a specific OBS setup for polished demos (1080p/4K, 30/60 fps, mic filters, separate app audio, cursor highlighting, hotkeys, and recommended recording settings).

clipchamp.com is easier if you want something simple and don't need much control. Its screen recorder can include system audio when the recording interface provides the Share system audio option.

For live software demos on Windows with system audio from apps, I’d pick based on how polished you need the final video to be:

Best overall: OBS Studio (free)

Best for: product demos, engineering walkthroughs, webinars, live presentations, recording multiple sources.

Why it fits:

• Captures your screen, app windows, microphone, webcam, and desktop/system audio.
• Lets you separate audio tracks (e.g., app sound vs your narration) for editing later.
• Handles long recordings without watermarks or time limits. zapier.com

Typical setup:

• Sources
  • Window Capture → your app/demo
  • Display Capture → full screen if needed
  • Audio Output Capture → system/app audio
  • Audio Input Capture → your mic
• Enable separate audio tracks if you plan to edit.

Downside: it is more “broadcast studio” than “press record and go.” zapier.com

Best polished demo workflow: Camtasia

Best for: customer demos, training videos, tutorials, sales enablement.

Advantages:

• Records screen + system audio + mic.
• Built-in editor for:
  • zooming into UI areas
  • cursor effects

  • captions
• Faster to turn a raw demo into a professional video than an OBS → editor workflow. kayatoday.com

Tradeoff: paid software.

Best for quick sharing: Loom

Best for: sending a demo to coworkers/customers quickly.

Good:

• Very fast start/stop/share workflow.
• Good for async product walkthroughs.

Less ideal:

• Less control over production quality.
• Not my first choice for recording a flagship demo video. toolradar.com

My recommended setups

1. Internal engineering/product demos

OBS Studio + good USB microphone
Record locally, edit only if needed.

2. Customer-facing software demos

Camtasia
Record → trim mistakes → add zooms/callouts → export.

3. Live webinar-style demos

OBS Studio
Add scenes:

• Intro slide
• Webcam + app
• Full-screen app
• Q&A layout

Windows audio tips

For reliable app audio capture:

• Use Application Audio Capture in newer OBS versions when available, so you can capture only the demo app instead of all system sounds.
• If you’re using Teams/Zoom/browser audio, test beforehand because app routing can vary.
• Record your mic separately from system audio so you can fix volume later.

If you want the simplest “hit record and deliver a professional software demo,” I’d choose Camtasia. If you want maximum control and zero cost, choose OBS Studio. zapier.com

For live software demos on Windows, I’d use OBS Studio.

It’s particularly good for your use case because it can capture:

• Your screen or a specific application window
• System/app audio
• Your microphone, independently
• Webcam, if wanted
• Separate audio sources/mixes, so you can control the demo app, mic, and other sounds independently. OBS specifically supports per-application audio capture on Windows. OBS Studio OBS Studio

obsproject.com

What I'd set up

For a typical software-demo recording:

OBS
├── Display Capture / Window Capture
├── Application Audio Capture → demo app
├── Microphone → your voice
└── Optional Webcam

The big advantage is Application Audio Capture: you can capture the audio coming from the application you're demonstrating without necessarily recording every other sound your PC makes. OBS Studio

Alternatives

• Windows Snipping Tool — easiest, built into Windows 11, but much more limited for a polished demo workflow. It can record a selected region of the screen. Microsoft Support
• Xbox Game Bar — very easy and can include system audio, but it's designed more around quick game/app clips than controlled software demos. Microsoft Support
• Clipchamp — useful if you want recording plus straightforward editing, though its audio capture has more limitations depending on what you're recording. Microsoft Support

My pick: OBS Studio. If you're recording demos for work, tutorials, YouTube, or product walkthroughs, the extra 10–15 minutes spent configuring OBS is well worth it.

If you tell me what app(s) you're demoing and whether you want your microphone + app audio on separate tracks, I can give you the exact OBS setup/settings I'd use.

For live software demos on Windows where you want the app/system audio captured reliably, I’d use OBS Studio.

My recommendation: OBS Studio

OBS Studio is free, lightweight, and particularly good for software demos because you can capture both the screen and individual applications' audio.

obsproject.com

Why it fits your use case:

• Window or full-display capture for the demo itself. OBS Studio
• Per-application audio capture on Windows 10/11, so you can capture audio from, say, Chrome, Teams, a development environment, or another app independently. OBS Studio
• Microphone + application audio mixing, with separate volume controls and filters. OBS Studio OBS Studio
• You can record multiple audio tracks, which is useful if you want to adjust your narration and demo audio separately afterward. OBS Studio
• It's free and open source. OBS Studio

Simple setup I'd use

In OBS:

1. Add Window Capture for the application you're demonstrating.
2. Add Application Audio Capture and select that same application.
3. Add Audio Input Capture for your microphone.
4. Disable global Desktop Audio if you're using Application Audio Capture, so you don't accidentally record the same sound twice and create an echo. OBS Studio
5. Record to MKV, then remux to MP4 afterward if you need an MP4 deliverable.

If you're demonstrating several apps, you can give each its own audio source and control their levels independently.

Alternatives

• Camtasia — better if your priority is easy recording + polished editing rather than live production. It supports recording system audio and microphone audio and is specifically aimed at tutorials/product demos. TechSmith Assets
• Windows Snipping Tool — fine for very quick screen clips, but much less capable for controlled audio capture. Microsoft Support
• Clipchamp — convenient if you already use Microsoft's ecosystem, but its audio capture has more limitations depending on what you're recording. Microsoft Support

Bottom line: For a developer/product demo where you want screen + app audio + microphone + control over individual audio sources, I'd pick OBS Studio. For a polished, edited tutorial with minimal setup, I'd pick Camtasia.

For Windows, OBS Studio is probably the best choice. It’s free, reliable, and can capture both your software demo and app/system audio.

My recommendation

• OBS Studio — best overall for polished software demos.

• Capture a specific app/window or your entire display.
• Record desktop/system audio from apps.
• Capture your microphone separately.
• Multiple audio tracks, so you can edit mic and system audio independently afterward.
• Supports hotkeys, scenes, webcam overlays, and high-quality recording.
• obsproject.com
• Windows Snipping Tool / Xbox Game Bar — easiest if you just need a quick screen recording, but less flexible for controlling audio sources and producing polished demos.
• Camtasia — worth considering if you want recording plus a very easy video editor for callouts, zooms, cursor effects, etc. It's paid. techsmith.com

For your specific use case

I'd set up OBS like this:

Video

Display Capture or Window Capture → your application

Audio

Desktop Audio → system/app sounds
Mic/Aux → your microphone

Then record to MKV and let OBS automatically remux to MP4 afterward. If you're demoing software with lots of UI interaction, I'd also enable cursor capture.

One particularly useful feature is separate audio tracks: you can put your microphone on one track and application/system audio on another, which makes it much easier to fix the balance in editing.

If you tell me whether you want just the app's audio (e.g. Chrome/Spotify/game audio) or all Windows system audio, I can give you the exact OBS audio setup.

For live software demos on Windows, especially if you need to capture system/app audio cleanly, I’d use OBS Studio.

Best choice: OBS Studio

obsproject.com

It’s free, and it’s particularly well suited to software demos because you can:

• Capture a specific application window rather than your entire desktop.
• Capture audio from individual applications on Windows 10/11.
• Record your microphone and app audio separately.
• Switch between scenes during a live demo.
• Add your webcam, overlays, cursor, etc.
• Record while also streaming if you ever need to.
• Use separate audio tracks if you want more control during editing. OBS Studio OBS Studio

For example, you could set up:

Scene: Demo

• Window Capture → your application
• Application Audio Capture → your application
• Audio Input Capture → your microphone
• Webcam → optional

OBS's Application Audio Capture lets you select the specific window/application whose audio you want, which is much better than simply recording all Windows desktop audio. OBS Studio

If you want something extremely simple: Clipchamp

Microsoft Clipchamp is easier to learn and is already available on Windows 11. Its screen recorder can capture a window, screen, or browser tab, and its work/school version can include system audio. Microsoft Support Microsoft Support

The catch: OBS is considerably better if your requirement is specifically “capture audio from this app while I'm demoing it.” Clipchamp's browser-based recording has more limitations around system/app audio. Microsoft Support

My recommendation

I'd go with OBS. For your use case, I'd configure it so your demo application's audio, microphone, and possibly other apps are separate sources/tracks. That gives you much more control and avoids the common problem of your microphone and system audio being baked into one track.

If you tell me what you're demoing (e.g. Chrome web app, VS Code, desktop app, game) and whether you're using headphones, I can give you the exact OBS setup for clean app audio + mic.

For recording live software demos on Windows with system audio from apps, the best choice depends on whether you want a polished tutorial, a quick walkthrough, or a live presentation recording.

Best overall: OBS Studio

obsproject.com

Best for: professional demos, tutorials, product walkthroughs, webinars, YouTube, internal training.

Why it’s usually the top pick:

• Captures screen + app audio + microphone separately
• Lets you mix audio levels live
• Records in high quality (1080p/1440p/4K)
• Supports scenes (e.g., full screen → webcam → slides → app)
• Free and widely used

Recommended setup:

• Sources - Display Capture (your monitor)
• Application Audio Capture (specific app audio, if available)
• Audio Input Capture (your mic)
• Webcam (optional)
• Audio mixer - Keep app audio around -20 to -10 dB
• Keep voice around -12 to -6 dB

For Windows 11, OBS can capture individual apps using Application Audio Capture, which is cleaner than recording all system sounds.

Easiest polished option: Camtasia

techsmith.com

Best for: business demos, training videos, customer-facing tutorials.

Advantages:

• Much easier than OBS
• Built-in editing
• Cursor highlighting
• Zoom/pan effects
• Callouts and annotations
• Good audio cleanup tools

Downside:

• Paid
• Less flexible for live production

Best for product demos with narration: Screen Studio

screen.studio

Best for: very polished SaaS/product demos.

Good features:

• Automatic zooms around clicks
• Smooth cursor animations
• Clean presentation style

Note: It is primarily known for macOS; Windows users may want OBS/Camtasia alternatives.

If you need live meetings + demos: Microsoft Teams or Zoom Video Communications

Use their screen-sharing recording if you need:

• A customer demo
• Remote attendees
• Simple recording without editing

For higher quality recordings, many people still record locally with OBS and use Teams/Zoom only for the live session.

Audio setup recommendations

If you want app audio only

Use:

• OBS → Application Audio Capture
• Or Windows 11 → Settings → System → Sound → Volume Mixer → per-app routing

If you want app audio + your voice

Use:

• OBS
• USB microphone or headset mic
• Separate tracks: - Track 1: final mix
• Track 2: microphone
• Track 3: system/app audio

This makes editing much easier.

My default recommendation

For most Windows software demos:

1. OBS Studio → recording engine
2. A decent USB mic → voice quality
3. DaVinci Resolve (free editor) → trimming, captions, polishing

That gives you a professional workflow without paying for a subscription.

If you tell me whether this is for YouTube/tutorials, sales demos, internal training, or live customer calls, I can suggest a more specific setup.

That gives you a professional workflow without paying for a subscription.

For live software demos on Windows, I’d use OBS Studio.

It’s particularly good for your use case because you can capture specific application windows and their audio, rather than just recording whatever comes out of the whole PC. OBS supports per-application audio capture on Windows 10/11, and you can keep each app as a separate audio source. OBS Studio OBS Studio

My recommended setup

• OBS Studio — screen/window recording
• Application Audio Capture — capture audio from the app you're demonstrating
• Microphone input — your narration
• Window Capture — capture just the application rather than your entire desktop
• Separate audio tracks — useful if you want to edit narration and app audio independently afterward

For example, you could have:

OBS
├── Demo App — Window Capture
├── Demo App — Application Audio
├── Microphone — narration
└── Webcam — optional

OBS specifically recommends disabling its global Desktop Audio when you're using Application Audio Capture sources, which prevents duplicate audio/echo. OBS Studio

What about Clipchamp?

Microsoft Clipchamp is easier if you just want a quick recording, and its work/school version can capture system audio when recording a screen/window. support.microsoft.com

But for live software demos, I'd choose OBS because you get much finer control over:

• which application's audio is recorded
• microphone vs. application volume
• multiple audio sources
• scenes
• webcam overlays
• hotkeys
• recording quality
• separate audio tracks

Bottom line: OBS Studio is the one I'd use. If you tell me whether you're demoing desktop apps, browser apps, or both, I can give you a clean OBS setup that captures the app audio without accidentally recording Slack/Teams/notifications in the background.

Why OBS is the best fit

• Captures a specific application/window rather than forcing you to record the whole desktop.
• Captures application audio separately on Windows 10/11, so you can record audio from your demo app without necessarily capturing every other sound. OBS Studio
• You can add your microphone as a separate audio source, then adjust mic/app volumes independently.
• You can have webcam + screen + app audio + mic all in one recording.
• You can create scenes such as Demo, Full Screen, and Demo + Webcam and switch between them during a live presentation.
• It's free, open source, and designed specifically for recording/streaming. OBS Studio

My recommended setup

For a typical software demo, I'd configure OBS roughly like this:

Scene: Software Demo

Sources:
├── Window Capture → your application
├── Application Audio Capture → your application
├── Audio Input Capture → microphone
└── Video Capture Device → webcam (optional)

OBS's Application Audio Capture lets you select the particular application whose audio you want. If you use that rather than global Desktop Audio, OBS recommends disabling the global Desktop Audio source to avoid an echo/double capture. OBS Studio

For example, if you're demoing a browser app that plays sounds, you can capture the browser's window and its audio while keeping random Windows notification sounds out of the recording.

Other options

• Xbox Game Bar — easiest if you just want Win + G → record. It can include system/app audio, but it's much less flexible than OBS. Microsoft Support
• Microsoft Clipchamp — convenient if you also want simple editing afterward, but its straightforward screen-recording audio workflow is more limited; Microsoft specifically notes browser-tab audio capture in some recording modes. Microsoft Support
• Snipping Tool — great for quick screen clips, but I'd choose OBS for a polished live demo. Microsoft Support

Bottom line: for recurring product/software demos, OBS is the one I'd pick. It gives you the most control over exactly which app, which audio, and which microphone end up in the recording.

If you tell me what you're demoing (browser, desktop app, game, terminal, etc.) and whether you want your microphone/webcam included, I can give you the exact OBS setup/settings.

For recording live software demos on Windows with system/app audio, the best choice depends on whether you need editing, webcam, streaming, or just clean demo capture. These are the strongest options:

Best overall: OBS Studio

Best for: professional demos, tutorials, product walkthroughs, webinars, YouTube, internal training

Why it’s usually the go-to:

• Captures screen + system audio + microphone separately
• Lets you record specific windows/apps instead of the whole desktop
• Supports multiple audio tracks (e.g., app audio separate from narration)
• Free and open source
• Excellent quality control (resolution, bitrate, encoding)
• Works well with Windows GPU encoders (NVENC, AMD, Intel Quick Sync)

Recommended setup:

• Display Capture or Window Capture → your demo app
• Application Audio Capture (Windows 10/11) → app sounds only
• Mic/Aux → your narration
• Record format: MKV (safer if OBS crashes), then remux to MP4

For the cleanest professional setup

I’d use:

OBS Studio + a decent USB microphone + separate audio tracks

Example:

• Track 1: application/system audio
• Track 2: microphone narration
• Track 3: backup mic or meeting audio

This lets you:

• Fix narration volume later
• Remove mistakes without rerecording
• Balance app sounds vs voice

A few Windows audio tips

• In OBS, avoid capturing "Desktop Audio" if you only want one app’s sound; use Application Audio Capture when possible.
• Use headphones while recording to prevent echo.
• Disable notification sounds (Teams, Outlook, Slack, Windows notifications).
• Record at 1080p/60fps for UI demos unless the software is mostly static, where 30fps is fine.

For most software demos, I’d pick OBS Studio unless you specifically want built-in editing, in which case Camtasia is worth considering.

For live software demos on Windows, I’d use OBS Studio. It’s the best fit if you want reliable screen capture plus system/app audio and control over exactly what gets recorded.

My recommendation: OBS Studio

obsproject.com

It can:

• Capture an entire monitor, a specific application window, or a game.
• Capture audio from individual applications on Windows 10/11 using Application Audio Capture. OBS Studio
• Record your microphone separately from the application audio.
• Put different audio sources on separate tracks, which is useful if you want to adjust narration vs. demo audio afterward. OBS Studio
• Handle webcam overlays, cursor effects, scenes, hotkeys, etc.
• Record locally without requiring an online service.

A good setup for a software demo would be:

OBS
├── Screen/Window Capture → your application
├── Application Audio Capture → application/system sound
├── Mic/Aux → your microphone
└── Optional Webcam → presenter camera

Important: If you're using Application Audio Capture, OBS recommends disabling its global Desktop Audio source to avoid capturing the same sound twice and creating an echo. OBS Studio

What about Clipchamp?

clipchamp.com

It's easier if you want quick recordings + basic editing, but I wouldn't pick it for serious live software demos. Microsoft's current documentation says system-audio capture is available when selecting a screen/window in the work/school recorder, while some personal-account/browser recording scenarios have more limited audio behavior. support.microsoft.com support.microsoft.com

Bottom line

For your use case, I'd go with OBS Studio. If you tell me whether you're demoing a desktop app, browser app, or both, I can give you an ideal OBS setup—including the exact audio settings so your app sounds and microphone don't interfere with each other.

For live software demos on Windows, I’d use OBS Studio. It’s free, reliable, and much better suited than the built-in Windows recorder when you need control over both video and audio.

obsproject.com

My recommended setup

• Screen/window: Use Window Capture if you're demonstrating one application, or Display Capture if you need to move between apps. OBS supports both. OBS Studio
• App audio: Use Application Audio Capture to capture audio from a particular app—e.g. your browser, demo software, Teams, etc.—without necessarily recording everything else on your PC. OBS Studio
• Your voice: Add your microphone as an Audio Input Capture source.
• System audio: If you want all computer audio, OBS can capture your desktop/output audio directly. OBS Studio OBS Studio
• Multiple apps: You can create separate audio sources for different applications and control their volumes independently. That's particularly useful for demos. OBS Studio

For example, I'd set up an OBS scene like:

DEMO SCENE
├── Window Capture — software you're demonstrating
├── Webcam — optional
├── Microphone — your narration
├── Application Audio — demo application's sound
└── Application Audio — browser/video/etc.

One nice advantage is that OBS 30.1+ can capture audio directly alongside Window Capture or Game Capture, so the setup can be even simpler. OBS Studio

What about Windows' built-in tools?

Snipping Tool is fine for quick recordings, but I wouldn't choose it for serious/live demos. Windows 11 includes video recording, but you don't get OBS's scene management and detailed per-application audio mixing. Microsoft Support

Xbox Game Bar is another easy option and can include system audio, but it's oriented more toward game/application clips than polished software demonstrations. Microsoft Support

Bottom line: OBS Studio + Application Audio Capture is the combination I'd pick. It gives you the most control while keeping the setup free and relatively straightforward. OBS Studio OBS Studio

If you tell me whether you want to record locally, livestream, or do both, I can give you a clean OBS setup with the exact audio/video settings I'd use for a professional software demo.

For recording live software demos on Windows with system/app audio, the best choice depends on whether you want a polished tutorial, a quick walkthrough, or a live presentation recording.

Best overall: OBS Studio

obsproject.com

Best for: professional demos, training videos, YouTube, webinars, technical walkthroughs.

Why it’s a strong choice:

• Captures specific application windows (instead of your whole desktop)
• Records system audio from apps
• Supports microphone + app audio mixing
• Lets you add webcam overlays, callouts, images, and scenes
• Free and has no recording length limits
• Excellent video quality control (1080p/4K, bitrate, codecs)

Typical setup:

• Sources → Window Capture → select your app
• Sources → Audio Output Capture → capture Windows/app sounds
• Sources → Audio Input Capture → microphone
• Record to MKV (safer) and remux to MP4 afterward

For Windows 11, OBS can use the built-in application audio capture features, or you can route audio with tools like VB-CABLE if you need more control.

• OBS Studio + VB-Audio VB-CABLE

vb-audio.com

This gives you a more "studio" setup:

• App audio → Track 1
• Mic → Track 2
• Discord/Teams → Track 3
• Music → Track 4

My recommended setups

Quick internal demo

• Loom
• USB headset mic
• 1080p recording

Professional software walkthrough

• OBS Studio
• Good USB microphone
• Window Capture
• Application Audio Capture
• Record in MKV

Training course / customer-facing videos

• Camtasia
• OBS for capture
• Edit in Camtasia

For most Windows software demos, I’d start with OBS Studio because it gives you the best quality and control without a subscription.

For recording live software demos on Windows with system/app audio captured, these are the best options depending on what you need:

Best overall: OBS Studio

obsproject.com

Best for: professional demos, tutorials, webinars, product walkthroughs, YouTube videos.

Pros:

• Captures your screen, webcam, microphone, and desktop/app audio
• Free and open source
• Can record separate audio tracks (e.g., your mic vs app sounds)
• Supports scenes (switch between full screen, camera, slides, browser, etc.)

Typical setup:

1. Add Display Capture or Window Capture → your demo app
2. Add Audio Output Capture → Windows system audio
3. Add Audio Input Capture → your microphone
4. Record

Tip: In newer Windows versions, OBS can capture individual application audio using Application Audio Capture (Windows 10/11 dependent), which is useful if you only want one app’s sound.

Easiest polished option: Camtasia

techsmith.com

Best for: business demos, training videos, internal documentation.

Pros:

• Very easy editing workflow
• Automatically captures screen + system audio + mic
• Great annotations, zoom effects, callouts
• Better for non-video-editors

Cons:

• Paid
• Less flexible than OBS for live production

Best for quick clips: Microsoft Clipchamp

clipchamp.com

Best for: short demos, bug reports, quick walkthroughs.

Pros:

• Built into Windows 11
• Simple interface
• Good for trimming and sharing

Cons:

• Not as powerful for complex demos

Best if you want remote demos/meetings: Zoom Video Communications or Microsoft Teams

zoom.com
microsoft.com

Useful if you are presenting live and want:

• screen sharing
• participant interaction
• recording
• system audio sharing

My recommendation by use case

For a professional software demo, I’d use OBS Studio + a decent USB microphone + separate audio tracks. It gives you the most control and avoids having to redo a demo because the app audio or narration was recorded poorly.

For Windows, I’d recommend OBS Studio. It’s free, reliable, and particularly good for software demos because you can capture:

• Your screen or a specific application window
• System/app audio
• Your microphone separately
• Webcam, if needed
• Multiple audio tracks for easier editing later
• High-quality recordings without watermarks

A good demo setup is:

OBS Studio
→ Display/Window Capture
→ Application/system audio capture
→ Microphone
→ Optional webcam
→ Record to MKV (then remux to MP4)

If you want something simpler than OBS, Windows 11’s Snipping Tool/Game Bar can handle basic screen recording, but OBS gives you much better control over app audio and presentation quality.

If you're recording live demos for YouTube, sales calls, tutorials, or product walkthroughs, I can also recommend the best setup/settings (resolution, FPS, bitrate, audio routing, etc.) for your particular use case.

For Windows, I’d use OBS Studio. It’s free, reliable, and particularly good for live software demos because you can capture:

• Your entire screen or a specific application/window
• System/app audio
• Your microphone separately
• Webcam
• Multiple scenes (e.g. intro → demo → slides)
• High-quality recordings without watermarks

Best setup for a software demo

OBS Studio + application/window capture + desktop audio + microphone

A useful audio setup is:

• Desktop Audio: captures sound from the apps you're demonstrating
• Mic/Aux: captures your voice
• Use the Audio Mixer to adjust the two independently
• Record to MKV (safer if OBS crashes), then remux to MP4 afterward

If you specifically need to capture only one application's audio rather than all Windows system audio, OBS on modern Windows versions can do this with Application Audio Capture. That's especially useful if you want, say, your browser's audio but not Slack/Teams notifications.

If you tell me whether you're recording Zoom/Teams demos, browser apps, desktop software, or coding demos, I can give you the ideal OBS settings and audio routing.

For Windows, I’d use OBS Studio. It’s free, reliable, and particularly good for software demos because you can capture both your screen/app and system audio.

Best options

• OBS Studio — best overall

• Captures a specific window, monitor, webcam, and microphone.
• Captures system/app audio independently from your microphone.
• Lets you mix and adjust audio levels live.
• Excellent for recording demos locally at high quality.
• Free and open source.
• Windows Snipping Tool — simplest

• Built into Windows 11.
• Good for quick screen recordings.
• Much less control over audio, scenes, cameras, and production.
• Xbox Game Bar — quickest for a single app

• Built into Windows.
• Can capture an app and system audio with minimal setup.
• Better for casual recordings than polished software demos.
• Camtasia — best if you want easy editing afterward

• Paid.
• Much easier than OBS for editing, annotations, zooms, callouts, etc.
• Good choice if the demo needs to become a polished tutorial/video.

My recommendation

If you're doing live software demos where you want your voice + application/system audio + screen, use OBS Studio.

A typical setup would be:

Screen/App capture ──┐
                     ├── OBS ──> MP4 recording
System/app audio ────┤
                     │
Microphone ──────────┘

One important distinction: if you need to capture audio from only one application (e.g. your demo app) while excluding Discord, browser music, notifications, etc., OBS can do that on modern Windows using Application Audio Capture. That's much better than simply recording all system audio.

If you tell me what kind of demo you're recording (e.g. SaaS/web app, desktop app, game, coding demo) and whether you need your microphone + webcam, I can give you the exact OBS setup and audio settings.

For live software demos on Windows, I’d use OBS Studio. It’s the best fit if you want clean screen capture and reliable control over app/system audio.

My recommendation: OBS Studio

obsproject.com

It gives you:

• Window Capture — record just the application you're demoing instead of your entire desktop.
• Application Audio Capture — capture audio from a specific app, such as Chrome, Teams, a local application, etc. OBS supports per-application audio on Windows 10 2004+ and Windows 11. OBS Studio
• Microphone + app audio mixing — independently control your voice and the demo's audio.
• Multiple scenes — e.g. intro → full-screen demo → webcam + demo → closing screen.
• High-quality recording without the limitations of Microsoft's built-in tools.
• Separate audio tracks, which is particularly useful if you want to edit your voice and application audio independently afterward. OBS Studio

A particularly nice setup for a software demo would be:

OBS
├── Window Capture
│   └── Your application
├── Application Audio Capture
│   └── Your application / browser
├── Audio Input Capture
│   └── Your microphone
└── Optional Webcam

If you're capturing multiple apps, OBS can give each application its own audio source. OBS recommends disabling its global Desktop Audio source when doing this, so you don't accidentally capture the same audio twice and create an echo. OBS Studio

If you want something dead simple

Xbox Game Bar is built into Windows and can record an app with system audio. Win + Alt + R starts/stops recording, and its settings let you choose to include all computer sounds. Microsoft Support

It's good for "I need to record this right now", but I'd choose OBS for professional demos.

Snipping Tool is another built-in option on Windows 11, but I'd favor it for quick screen recordings rather than polished software demos. Microsoft Support

What I'd use

Bottom line: install OBS Studio. For your particular requirement—live software demos where the audience needs to hear audio coming from the apps—its Application Audio Capture feature is the big advantage. OBS Studio

If you tell me whether you're demoing browser apps, desktop apps, or both, I can give you the exact OBS setup (sources, audio settings, resolution/FPS, and recording format) I'd use.

For Windows software demos where you want the app’s system audio captured, I’d use OBS Studio.

obsproject.com

Best options

• OBS Studio — best overall. Free, open-source, and gives you excellent control over screen/window capture, microphone audio, and per-application audio. On Windows 10/11, you can add an Application Audio Capture source and choose exactly which app's audio to record. OBS Studio OBS Studio
• Microsoft Clipchamp — easiest. Good if you just want quick demos with minimal setup. It can record screen + system audio, but Microsoft's current documentation indicates system-audio capture is more limited depending on whether you're recording a browser tab or using the work/school recorder. Microsoft Support Microsoft Support
• Screen Studio — great-looking demos, but not my Windows recommendation. Its audio workflow is excellent, including selecting particular apps, but its current documentation primarily targets macOS. Screen Studio Screen Studio

What I'd use for your situation

OBS + Application Audio Capture is the sweet spot if you're demonstrating software such as a desktop app, browser, IDE, game, etc.

A typical setup would be:

1. Add Window Capture for the application you're demonstrating.
2. Enable Capture Audio on that Window Capture, or add Application Audio Capture separately.
3. Add your microphone as an Audio Input Capture.
4. Disable global Desktop Audio if you're using per-app capture, to prevent duplicate/echoing audio. OBS Studio
5. Record to MKV, then remux to MP4 if needed.

The particularly nice part is that you can have your voice on one audio source and the application's sound on another, so you can adjust them independently afterward.

If you tell me what kind of demo you're recording (e.g. Chrome web app, Electron app, game, VS Code/terminal, Zoom/Teams), I can give you the ideal OBS setup and settings for it.

For Windows software demos, I’d use OBS Studio. It’s free, very capable, and—importantly for your use case—it can capture audio from individual applications, not just all system audio. OBS supports Windows 10/11 and is currently at version 32.2.2. OBS Studio OBS Studio

obsproject.com

My recommendation

OBS Studio + Application Audio Capture

You can set up a scene with:

• Window Capture — records just your app/demo window.
• Application Audio Capture — captures audio from, say, Chrome, Teams, Slack, your app, etc.
• Mic/Aux — your narration.
• Webcam — optional.
• Multiple audio tracks — useful if you want to adjust your voice and app audio separately afterward.

OBS's Application Audio Capture works on Windows 10 2004+ and Windows 11. You can select individual applications as audio sources. OBS Studio

For example, you could have:

VIDEO
├── Your software demo window
└── Webcam (optional)

AUDIO
├── Your microphone
├── Chrome audio
└── Demo app audio

That is particularly nice for demos because you don't have to record everything your computer is playing. You can isolate the application's audio you actually want. OBS Studio

What about Camtasia?

If you want something much easier to use and edit afterward, I'd consider Camtasia. It's more of an all-in-one screen recorder + video editor, whereas OBS is primarily a capture/production tool.

Camtasia supports recording the screen, microphone, camera, and system audio, so it's a good choice if your workflow is:

record demo → cut mistakes → add zooms/callouts → export polished video. TechSmith Download

• TechSmith Camtasia 2024 - $52.07 (Exclusive Books Online)

Which I'd pick

For your specific question, I'd start with OBS. You don't need a capture card or virtual audio cable for most normal Windows apps anymore—the built-in Application Audio Capture functionality handles this. OBS Studio

If you tell me what kind of software demos you're recording (e.g. Chrome web app, Electron app, desktop app, games), I can give you the exact OBS setup—including the best resolution/FPS/audio settings and how to make the app audio + microphone sound good.

For Windows software demos where you want the screen + app/system audio + your microphone, I’d use OBS Studio.

Best choice: OBS Studio

obsproject.com is free, open-source, and particularly good for demos because you can control exactly which windows and audio sources get recorded. It supports Windows 10/11. OBS Studio OBS Studio

The big advantage for your use case is Application Audio Capture. On Windows, OBS can capture audio from individual applications—e.g. Chrome, your IDE, a demo app, Teams, etc.—rather than simply recording everything coming out of the speakers. OBS Studio

A good demo setup would be:

• Window Capture or Display Capture → your software demo
• Application Audio Capture → audio from the app you're demonstrating
• Audio Input Capture → your microphone
• Optional Webcam → your face
• OBS's mixer → independently adjust your voice vs. application audio

OBS 30.1+ can also attach audio directly to Window Capture/Game Capture sources, which makes the setup even simpler. OBS Studio

obsproject.com

If you want something dead simple

Xbox Game Bar is already built into Windows and can record an app with system audio. Microsoft documents an "All" audio option that includes app/system sounds, and Win + Alt + R starts/stops recording. Microsoft Support

I'd choose it for a quick one-off recording, but not for polished software demos. OBS gives you much better control over audio, resolution, scenes, webcam placement, and recording quality.

What I'd personally use

OBS + a decent USB mic + headphones.

For software demos, I'd configure OBS so that your microphone and the demo application's audio are separate sources/tracks. That gives you much more flexibility if, for example, the application is too loud or you want to remove your voice during editing.

One important tip: if you're capturing individual applications in OBS, don't simultaneously capture the same audio through global Desktop Audio, or you can get an echo/double audio signal. OBS specifically recommends disabling the global Desktop Audio source when using Application Audio Capture this way. OBS Studio

If you tell me what kind of demos you're recording (e.g. browser SaaS demos, coding/IDE demos, games, Electron apps, AI voice demos), I can give you an ideal OBS setup with the exact sources and audio settings.

For Windows software demos with app/system audio, my first choice is OBS Studio.

OBS Studio is free, open-source, and currently supports Windows 10/11. obsproject.com

Why OBS is a great fit

• Screen/window capture — record your whole desktop or just the application you're demonstrating.
• System/app audio — on Windows 10 2004+ and Windows 11, OBS has Application Audio Capture, letting you capture audio from individual apps rather than everything your computer plays. obsproject.com
• Microphone + app audio simultaneously — useful for narrating a demo.
• Separate audio sources — you can independently control your voice, the demo application's audio, browser audio, etc.
• High-quality recording without requiring a webcam or streaming setup.
• No need for virtual audio cables in most cases. OBS's built-in application audio capture handles many apps directly. obsproject.com

Recommended setup

For a typical software demo, I'd configure one scene like:

Video

• Window Capture → your application
• Webcam → optional

Audio

• Application Audio Capture → the application you're demonstrating
• Mic/Aux → your microphone
• Optionally another Application Audio Capture → browser/Teams/etc.

If you're using application-specific audio sources, OBS recommends disabling the global Desktop Audio source to prevent duplicate audio/echo. obsproject.com

One alternative: Camtasia

If you want something more presentation/tutorial oriented and less technical than OBS, Camtasia is worth considering. It supports recording the screen, microphone, camera, and system audio, and then gives you a built-in editor for trimming, callouts, zooms, cursor effects, etc. download.techsmith.com

My pick:

• OBS → best if you mainly want to record clean demos and have control over audio/video.
• Camtasia → best if you want to record and heavily edit polished software tutorials afterward.

If you tell me whether you're recording a browser app, desktop app, or both, I can give you an ideal OBS setup (including exact audio settings and recording format).

For recording live software demos on Windows with system audio from apps, the best choices are usually:

1. OBS Studio — best overall (free)

OBS Studio

Best for: professional demos, tutorials, webinars, product walkthroughs.

Why it’s a strong choice:

• Captures screen, windows, webcams, microphones, and desktop/app audio
• Lets you record separate audio tracks (e.g., app audio vs your mic)
• Supports scenes (intro screen → demo → camera view → slides)
• No watermark, no recording limits
• Great quality control (resolution, bitrate, encoder)

Recommended setup:

• Sources
  • Display Capture or Window Capture → your demo app
  • Audio Output Capture → system/app sounds
  • Audio Input Capture → your microphone
• In Settings → Output, record as MKV (safer if OBS crashes), then remux to MP4 if needed.

Tip: If you need only one app’s audio rather than all Windows sounds, use Windows 11’s per-app audio routing or OBS plugins such as Application Audio Capture.

2. Camtasia — easiest polished workflow

TechSmith Camtasia

Best for: business demos, training videos, customer-facing tutorials.

Pros:

• Very easy editing after recording
• Built-in zooms, callouts, cursor effects
• Good microphone cleanup
• Captures system audio cleanly

Cons:

• Paid
• Less flexible than OBS for complex setups

3. ScreenFlow alternative note

ScreenFlow is excellent, but it is primarily for macOS, so it’s not a Windows option.

4. Microsoft Clipchamp — simple built-in option

Microsoft Clipchamp

Best for: quick recordings and basic edits.

Pros:

• Built into many Windows 11 installs
• Simple workflow

Cons:

• Less control over audio routing
• Not ideal for complex software demos

My recommendation by use case

For a typical software demo, I’d use OBS Studio + a good USB microphone + Window Capture + Application Audio Capture. That gives you the cleanest “product demo” style recording without paying for software.

For live software demos on Windows, I’d use OBS Studio. It’s free, reliable, and gives you much more control over both video and audio than the built-in Windows tools. obsproject.com

My picks

1. OBS Studio — best overall

• Capture your whole display, a specific application/window, webcam, etc.
• Capture system/application audio.
• On Windows 10/11, OBS supports per-application audio capture, so you can capture, say, Chrome or your demo app separately rather than recording every sound your PC makes. obsproject.com
• You can put your mic on a separate audio track and adjust levels independently.
• Excellent if you're doing technical demos and want a clean, professional recording.

Download OBS Studio

2. Camtasia — best if you want easy editing

• More polished/easier workflow than OBS.
• Records screen + microphone + system audio directly. support.techsmith.com
• Particularly nice if you'll cut mistakes, zoom into UI elements, add callouts, captions, arrows, etc.
• It's paid, though there's a trial.

Camtasia

3. Windows Snipping Tool — simplest

• Already built into Windows 11.
• Can record a selected region of the screen. support.microsoft.com
• But I wouldn't choose it for serious software demos where app audio + mic + control over individual audio sources matters.

What I'd personally use

For a typical demo:

OBS → Window Capture → Application Audio Capture → Microphone

For example:

Video
├── Demo application window
└── Webcam (optional)

Audio
├── Demo app audio
└── Microphone

OBS specifically recommends disabling its global Desktop Audio when you're using individual Application Audio Capture sources, which prevents duplicate/echoing audio. obsproject.com

One important advantage: if your demo involves multiple apps—e.g. Chrome + VS Code + a terminal—you can configure their audio independently. That makes OBS particularly good for software demos.

If you tell me what kind of demo you're recording (browser app, desktop app, coding/terminal, game, etc.), I can give you the exact OBS setup and recommended audio/video settings.

For live software demos on Windows, I’d use OBS Studio. It’s the best fit if you want professional-looking recordings and reliable control over app audio.

OBS Studio official site

Why OBS is the best choice

• Capture a specific application/window rather than your entire desktop.
• Capture audio from individual apps—for example, your demo app’s sound while excluding Slack/Teams notifications. OBS supports per-application audio capture on Windows 10 (2004+) and Windows 11. obsproject.com
• Record your microphone separately, so you can control your voice vs. application audio.
• Add a webcam, overlays, cursor effects, intro slides, etc.
• You can record multiple audio tracks, which is particularly useful if you want to edit your voice and system audio independently later. obsproject.com
• It's free and open source.

A good demo setup

In OBS, I'd make one scene with:

1. Window Capture — your software demo
2. Application Audio Capture — audio from the demo app
3. Audio Input Capture — your microphone
4. Video Capture Device — optional webcam
5. Optional Display Capture — useful when you need to demonstrate things outside the app

OBS specifically supports attaching audio directly to Window Capture/Game Capture, or adding an Application Audio Capture source separately. obsproject.com

One important tip: if you use Application Audio Capture, disable OBS's global Desktop Audio capture unless you actually need it. Otherwise you can end up recording the same audio twice and getting an echo. obsproject.com

What about the built-in Windows tools?

Snipping Tool is great for quick recordings, but I wouldn't choose it for polished live demos. Windows 11 includes screen recording, but it doesn't give you the same audio routing/mixing control as OBS. support.microsoft.com

Clipchamp can record screen + audio, but its system-audio support is more constrained depending on what you're recording; Microsoft's documentation specifically notes limitations around browser-tab audio. support.microsoft.com

Bottom line:
OBS Studio + Application Audio Capture is what I'd use. It gives you the most control without needing a virtual audio cable in the normal case.

If you tell me what kind of demo you're recording (browser app, desktop app, IDE, game, etc.) and whether you want your microphone + webcam, I can give you an ideal OBS setup with the exact sources and audio settings.

For live software demos on Windows, I’d use OBS Studio. It’s the best combination of recording quality, control, and reliable app-audio capture.

My recommendation: OBS Studio

OBS Studio

It can capture:

│   └── Your application
│
├── Audio Input Capture
│   └── Microphone
│
└── Optional: Webcam

You can also enable Capture Audio directly on a Window Capture/Game Capture source in newer OBS versions. obsproject.com

If you want something simpler

Microsoft Clipchamp is easier if you're doing basic screen recordings, particularly browser demos. It supports recording a screen/window and sharing system audio, although its system-audio workflow is more limited than OBS. support.microsoft.com

Xbox Game Bar is also built into Windows and can record an app with system audio, but I wouldn't choose it for polished software demos because you get considerably less control. support.microsoft.com

What I'd choose

For your use case, go with OBS. It's especially good if your demo involves something like a desktop app + browser + microphone and you want the recording to sound clean.

If you tell me whether you're demoing a browser app, desktop app, or both, I can give you the exact OBS setup/settings I'd use for a clean 1080p/60fps demo.

For live software demos on Windows, I’d use OBS Studio. It’s free, reliable, and gives you much more control over app/system audio than the built-in Windows tools.

OBS Studio official site

My recommendation: OBS Studio

It can capture:

• 🖥️ A specific application/window or your entire screen
• 🔊 System/desktop audio
• 🎵 Individual applications' audio — e.g. Chrome, Slack, Spotify, your demo app, etc.
• 🎙️ Your microphone separately
• 📷 Webcam/camera
• ⌨️ Hotkeys for starting/stopping recordings
• Multiple audio tracks, if you want to edit narration and app audio separately later

On current Windows versions, OBS has Application Audio Capture, which lets you select a particular application's audio rather than simply recording everything your computer plays. obsproject.com

A good setup for software demos

I'd configure an OBS scene roughly like:

Video

• Window Capture → your demo application
• Or Display Capture → entire screen if you're switching between apps

Audio

• Application Audio Capture → demo app
• Application Audio Capture → browser, if needed
• Mic/Aux → your microphone
• Disable global Desktop Audio if you're using application-specific sources, to avoid duplicate/echoed audio. obsproject.com

This is particularly nice for demos because you can have, for example:

Demo app: 100%
Browser: 60%
Your mic: 80%
Slack/notifications: completely excluded

OBS also supports hardware encoders such as NVENC, QuickSync, and AMD VCE where available, which can reduce the CPU load of recording. obsproject.com

What about the built-in Windows options?

Xbox Game Bar is fine if you want something extremely simple. It can record an app and include system audio, but it's much less flexible for polished demos. support.microsoft.com

Clipchamp is better if your priority is record → edit → export rather than sophisticated capture. Its screen recorder can include system audio in some recording modes, but there are limitations around browser/tab recording. obsproject.comsupport.microsoft.comsupport.microsoft.comsupport.microsoft.com

Snipping Tool is convenient for quick screen recordings, but I wouldn't choose it for serious demo production. support.microsoft.com

Bottom line: OBS Studio is the one I'd pick. It's especially good if you want clean recordings where your narration and application audio are independently controllable.

If you tell me whether you're demoing a desktop app, browser app, or terminal/CLI, I can give you the ideal OBS setup (including the exact sources and audio settings).

For live software demos on Windows, I’d use OBS Studio. It’s free, reliable, and gives you much more control over app audio than most simple screen recorders. obsproject.com

My recommendation: OBS Studio

OBS Studio

For your use case, set up:

• Window Capture → the app you're demonstrating
• Application Audio Capture → captures audio from that specific app
• Audio Input Capture → your microphone
• Optional Webcam → if you want your face on screen

OBS supports per-application audio on Windows 10/11, so you can capture, for example, Chrome audio without necessarily recording Slack/Spotify/other apps. You can also include audio directly with Window Capture or Game Capture. obsproject.com

A particularly nice setup for demos is:

Scene: Software Demo

┌─────────────────────────────┐
│                             │
│       App / Browser         │

│                             │
└─────────────────────────────┘
   🎙 Microphone
   🔊 App Audio

I'd also disable OBS's global Desktop Audio if you're using Application Audio Capture, to avoid capturing the same audio twice and creating an echo. obsproject.com

If you want something much simpler

Microsoft Clipchamp is a good alternative if you don't need OBS's control. Its screen recorder can record an entire screen, an application window, or a browser tab, and in Chrome/Edge you can select “Share system audio” to include audio played by the computer. obsproject.comsupport.microsoft.com

I'd choose:

Bottom line: use OBS if you're going to make demos regularly. It takes ~10 minutes to configure properly, but then you can hit Start Recording and have a repeatable setup every time.

For live software demos on Windows, I’d use OBS Studio. It’s the best fit if you want reliable screen capture and control over exactly which apps’ audio gets recorded.

OBS Studio

My recommendation: OBS Studio

It can capture:

• 🖥️ Your entire desktop or a specific application window
• 🔊 Audio from individual apps — e.g. Chrome, Slack, Teams, your app, etc.
• 🎙️ Your microphone
• 📹 Webcam, if desired
• 🎚️ Separate volume controls for each audio source
• ⌨️ Hotkeys for starting/stopping recordings
• 🎧 Multiple audio tracks if you want to edit narration and app audio separately later

On current Windows versions, OBS has a built-in Application Audio Capture source. You can select an application and capture its audio independently, rather than recording everything your PC is playing. obsproject.com

A good demo setup

I'd make one OBS scene like:

Video

• Window Capture → your software demo
• Optional Video Capture Device → webcam

Audio

• Application Audio Capture → your demo app
• Application Audio Capture → Chrome, if your demo involves browser audio
• Audio Input Capture → your microphone

That gives you a very clean recording where, for example, your app audio is at 80%, Chrome is at 40%, and your voice is at 100%.

OBS specifically recommends disabling its global Desktop Audio when you're using individual Application Audio Capture sources, otherwise you can end up recording the same audio twice and creating an echo. obsproject.com

If you want something dead simple

Xbox Game Bar is already built into Windows and can record an application with system audio. Win + Alt + R starts/stops recording. Microsoft documents an option to include all computer sounds. support.microsoft.com

But I'd choose it only for quick, disposable demos. You don't get nearly the same audio/video control as OBS.

Clipchamp is another easy option, but its system-audio support is more limited depending on how you're recording; Microsoft's documentation specifically notes browser-tab audio sharing for its basic screen recorder. support.microsoft.com

Bottom line

I'd pick OBS without hesitation for your use case. It gives you the most useful combination of live screen capture + system/app audio + microphone + control.

If you tell me whether you're demoing a browser app, desktop app, or both, I can give you the exact OBS sources/settings I'd use for a polished demo recording.

For live software demos on Windows, I’d use OBS Studio. It’s the best fit if you want reliable screen recording plus audio from specific apps, rather than just whatever happens to be playing through your speakers.

My picks

OBS Studio is particularly strong here: on Windows 10/11 it can capture audio from individual applications as separate sources. You can, for example, capture your demo app's audio while keeping Slack/Teams/notification sounds out of the recording. obsproject.com

Download OBS Studio

A typical setup would be:

• Window Capture → your software demo
• Application Audio Capture → the demo application's audio
• Audio Input Capture → your microphone
• Optional webcam/video capture → your face
• Record to MKV, then remux to MP4 if needed

If you want separate control over the app audio and your voice, OBS is especially nice because you can put them on separate audio tracks.

If you want something much simpler

Microsoft Clipchamp is convenient for quick demos. Its screen recorder can include system audio, and it has built-in trimming/editing. However, Microsoft's current documentation indicates that system-audio capture is tied to the browser-based screen-sharing flow, and the personal version has some limitations around what can provide audio. support.microsoft.com

If you're making professional product demos

Camtasia is worth considering if you want to record and then quickly turn the raw demo into a polished tutorial—with callouts, zooms, cursor effects, captions, etc. Its Windows recording flow also supports system audio. support.techsmith.com

Camtasia

Bottom line:
For your specific requirement—live software demos + Windows + system/app audio—I'd pick OBS Studio. It's free, very reliable, and gives you the most control over exactly which application's audio gets recorded.

If you tell me whether you're demoing a desktop app, browser app, or both, I can give you the ideal OBS setup/settings for it.

For Windows, OBS Studio is probably the best choice for what you described.

• OBS Studio — free, open-source, excellent for live software demos. It can capture a specific application/window or your entire screen, while also recording system/app audio and your microphone on separate tracks.
• Camtasia — easier to learn and particularly good if you want to edit the demo afterward with zooms, callouts, cursor effects, etc. Paid.
• Screen Studio — very polished, especially for making clean software/product demos, but it’s more geared toward presentation-style recordings than complex live setups.
• Xbox Game Bar — built into Windows and easy for quick recordings, but much less flexible for professional demos.

My pick: OBS Studio

For a typical software demo, I'd set it up roughly like:

Video

• Display Capture or Window Capture → your application
• Optional webcam → separate video source

Audio

• Desktop Audio → captures sounds from your apps
• Mic/Aux → your microphone
• Optionally route different apps to separate audio tracks if you want more control in editing

One particularly useful feature is Application Audio Capture in newer OBS versions, which lets you capture audio from a particular Windows application rather than blindly recording everything your PC plays.

If you're recording something like “I’m going to demo my app while talking, and I need the app's notification/sound effects captured cleanly”, I'd definitely use OBS.

For live software demos on Windows, I’d use OBS Studio. It’s the best fit if you want control over exactly what gets recorded, especially system/app audio + microphone + screen/window.

My recommendation: OBS Studio

OBS Studio — official download

It can capture:

• 🖥️ Your entire display or just a specific application window
• 🔊 Audio from individual apps — e.g. Chrome, Slack, Teams, your demo app, etc.
• 🎙️ Your microphone
• 📹 Webcam, if desired
• 🎚️ Separate audio levels/tracks so you can adjust things later

On Windows 10 (2004+) and Windows 11, OBS has Application Audio Capture, which lets you select a particular app and capture its audio separately. obsproject.com

A very clean setup for demos is:

Scene

• Window Capture → your application
• Application Audio Capture → your application
• Audio Input Capture → your microphone
• Optional webcam

That way, you aren't necessarily recording every sound your PC makes. OBS also supports capturing audio directly with Window/Game Capture on recent versions. obsproject.com

What I'd use for different situations

Xbox Game Bar can include all computer sounds and record an app with Win + Alt + R, so it's a good zero-setup option. support.microsoft.com

Clipchamp can also capture system audio, but its browser-based screen recording has some limitations around which audio sources it can capture. support.microsoft.com

Bottom line: If you're making recurring product/software demos, tutorials, or sales demos, use OBS. Spend 10 minutes setting up one good scene and you'll have a much better workflow than repeatedly fighting Windows' built-in recorder.

If you tell me what you're demoing (browser app, desktop app, terminal, etc.) and whether you want your mic + webcam, I can give you the exact OBS setup/settings I'd use.

For live software demos on Windows, especially if you need to capture the app's system audio + your microphone, I'd use OBS Studio.

My picks

Why OBS is my recommendation: it can capture a specific application/window and, on Windows 10 2004+ and Windows 11, capture individual applications' audio as separate sources. That means you can have, for example, Chrome audio on one track and your microphone on another. obsproject.com

A good demo setup

In OBS, I'd configure:

• Video: Window Capture or Display Capture
• App audio: Application Audio Capture → select the app you're demoing
• Microphone: Audio Input Capture → your mic
• Desktop Audio: Disable it if you're using per-application audio, to avoid recording the same sound twice. obsproject.com
• Recording: 1080p, 30 or 60 FPS
• Format: MKV while recording, then remux to MP4 if needed

The big advantage is that you don't have to rely on whatever is coming through your speakers/headphones. OBS can grab the application's audio directly.

If you want something dead simple

Windows 11's Snipping Tool now supports screen recording with audio in newer versions, so it's worth trying if you don't need separate audio tracks or a fancy setup. learn.microsoft.com

But for software demos, I'd still choose OBS because you can independently control the demo app, microphone, music/other apps, webcam, and audio levels.

If you tell me what you're demoing (e.g. browser app, Electron app, game, desktop SaaS) and whether you want your voice + app audio, I can give you the exact OBS setup I'd use.

For live software demos on Windows, I’d use OBS Studio. It’s free, lightweight, and gives you much more control than the built-in Windows recorder.

OBS Studio

My recommendation: OBS Studio

It handles:

• 🖥️ Window or entire-screen capture
• 🔊 System/app audio
• 🎙️ Microphone audio
• 📷 Webcam/picture-in-picture
• 🎚️ Separate volume controls for each source
• ⏺️ High-quality local recording
• Multiple scenes, so you can switch between things like “demo,” “webcam,” and “slides”

Most importantly for your use case, current OBS on Windows supports Application Audio Capture, letting you capture audio from individual apps rather than blindly recording everything your PC plays. You can also capture audio directly alongside a Window/Game Capture source. obsproject.com

A good demo setup

I'd configure an OBS scene roughly like:

If you're capturing a specific application's audio, OBS recommends disabling its global Desktop Audio source to avoid recording the same audio twice and creating an echo. obsproject.com

If you want the simplest possible option

Xbox Game Bar is already built into Windows and can record an app with system audio. Win + Alt + R starts/stops recording, and Windows lets you choose to include all computer audio. support.microsoft.com

I'd use it for quick throwaway recordings, but not for polished software demos.

If you want recording + serious editing

Camtasia is worth considering if you want to record the demo and then quickly clean it up afterward. It supports system audio as well as microphone recording and is designed specifically around screen-recording/editing workflows. www.techsmith.com

My ranking:

1. 🥇 OBS Studio — best overall; free and highly controllable
2. 🥈 Camtasia — best if you want easy post-recording editing
3. 🥉 Xbox Game Bar — best for extremely quick/simple recordings

For live software demos where you talk while clicking around an app, I'd pick OBS without hesitation.

For live software demos on Windows, I’d use OBS Studio.

Best options

OBS is my recommendation. It can capture a specific application window and its audio separately on Windows 10/11. You can, for example, record your IDE/browser/app while capturing audio from just Chrome or another application rather than blindly recording everything coming out of your speakers. obsproject.com

OBS Studio

A good setup for software demos

In OBS, I'd make one scene with:

• Window Capture → the app you're demonstrating
• Application Audio Capture → the app's sound
• Audio Input Capture → your microphone
• Optional Webcam
• Optional Display Capture → useful if you need to switch between several apps

OBS also lets you include audio directly with a Window Capture source on newer versions. obsproject.com

One particularly nice feature for demos is separate audio sources. You can have, say, Chrome audio, your demo application's audio, and your microphone as independent tracks, which makes fixing the mix afterward much easier. obsproject.com

When I'd pick Camtasia instead

If your workflow is "record demo → cut mistakes → add zooms/callouts → export polished video," I'd seriously consider Camtasia. Its recorder explicitly supports system audio alongside microphone, screen, and camera capture, and it has a much more approachable editing workflow than OBS. www.techsmith.com

Camtasia

My short recommendation:

• 🎥 Live demos / technical demos / lots of apps: OBS
• ✂️ Tutorial videos that need editing: Camtasia
• ⚡ "I just need to record this right now": Windows Clipchamp/Game Bar

If you're specifically demonstrating a local app + browser + terminal + microphone, I can also give you a clean OBS configuration that captures each application's audio separately without echo.
