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:

• A specific application/window rather than your whole desktop
• Audio from individual apps — e.g. your demo app, browser, Slack/Teams, etc.
• Your microphone independently
• Webcam, if you want it
• Multiple audio tracks, so you can edit your voice and app audio separately later

OBS has built-in Application Audio Capture on Windows 10/11. You can select the specific application whose audio you want, and OBS recommends disabling its global Desktop Audio source when doing this to prevent duplicate audio/echo. obsproject.com

A typical demo setup would be:

Scene: Software Demo

├── Window Capture
│   └── Your application
│
├── Application Audio 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

Microsoft Clipchamp

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

Download OBS Studio

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.
