Screen Recorder with Audio for Windows

SwiftRec captures your screen with both microphone and system audio mixed into a single MP4 file — no watermark, no login, no hassle. Hit a hotkey and record.

Why Record Screen with Audio?

You need audio in your recording. Maybe you're making a tutorial and talking over the footage, or capturing a gameplay session with commentary, or documenting a bug with system sounds included. The built-in Windows Game Bar won't record File Explorer and doesn't give you clean control over which audio tracks end up in the file.

SwiftRec mixes your mic and whatever is playing on your speakers into one MP4. Toggle each audio source on or off before you start — if you only want system sound (no mic), or only your voice (no background music), you choose. Both tracks go into the same file.

Common Recording Scenarios

Tutorial or how-to: Record Full Screen or a Window, turn the mic on (speaker off if the app has no background sound), set Mouse and Keystroke Indicators to on so viewers see every click and keystroke. Stop, and the MP4 is ready for editing or YouTube.

Game or application review: Capture a Window or Full Screen with both mic and speaker on. If you want a live reaction shot, toggle the optional webcam bubble. Your voice and game audio are already mixed into the file.

Bug report or quick demo: Use Region mode to draw around just the problem area. Mic on, speaker off. Record for 10 seconds, stop, and drop the MP4 into a ticket or chat thread. No need to edit.

Desktop or software walkthrough: Full Screen capture works best. Mic on. The app stays out of view — no overlay, no watermark clutter — so your recording looks professional.

Audio Mixing and Output

Both microphone and system audio are muxed into a single MP4 track. This means you don't get separate audio files or complicated post-work — open the MP4 in any media player or editor and both your voice and background sound are already there.

If you only need one audio source, simply leave the other icon off before pressing record. No audio processing or effects are applied; SwiftRec captures and mixes the raw streams.

The finished MP4 uses H.264 codec and is compatible with YouTube, most video editors, and any modern media player.

Questions About Audio Recording

Will the audio be out of sync?

No. SwiftRec muxes mic and system audio into one file on the fly, keeping them synchronized.

Can I record only system audio, no mic?

Yes. Toggle the mic icon off before you start. Only the speaker output goes into the MP4.

What if I want to hear myself while recording?

Your system sound plays normally in your ears while recording. SwiftRec captures the audio stream independently.

Does it work on Windows 10?

Yes. SwiftRec runs on Windows 10 (64-bit) and Windows 11. It also works on earlier Windows versions that have .NET Framework 4.7.2.

How do I install it?

No. Run the app from your user folder and record audio normally without elevation.

Is there a watermark on my audio or video?

No watermark anywhere — on video, audio, or the file metadata.

Getting Started

Download SwiftRec, run the Windows setup, and launch. Installs in about a minute. Set up a hotkey so you can start and stop recording without switching windows. Open the app settings, assign a global hotkey for record/stop, and you're ready.

Audio devices are detected automatically. If you have a microphone and speakers connected, both will appear in the mic and speaker toggles. Test a short recording first to make sure audio levels sound right to you.
