Record Your Computer Screen and Audio — Free Windows Tool

You need to capture what's happening on your screen along with audio from your microphone and speakers. SwiftRec does exactly that: one hotkey, one clean MP4 file, no account or watermark required.

What You Get

SwiftRec is a portable Windows screen recorder that captures video and audio in a single MP4 file. Press a hotkey to start, press it again to stop — the finished video lands in your Videos folder. That's the entire workflow.

Unlike the built-in Xbox Game Bar, SwiftRec records File Explorer, specific regions, and individual windows. You pick the source from the toolbar before you hit record: full screen, a single window, a free-form region, or one monitor only.

Audio is the core of what you're looking for. SwiftRec mixes your microphone and system audio into one track. If you're narrating a tutorial, both your voice and the background sound from the app or video stay synchronized in the output.

Common Scenarios

**Tutorials and how-tos:** Record a window or region, keep your microphone on, and leave system audio off so only your voice is heard. If you want to show clicks and key presses, toggle the keystroke indicator on before you record.

**Gameplay or software demos:** Use full-screen capture, enable both microphone and system audio, and you'll get the game audio plus your commentary in one file. (Always check the game's terms before recording.)

**Conference calls or webinars:** Capture a single window (the video call app) with your microphone on and system audio on. Both sides of the conversation will be in the output.

**Quick bug reports:** SwiftRec also takes still screenshots to PNG. Use the hotkey while not recording, draw a region around the issue, and send the image directly instead of a video.

Questions About Screen and Audio Recording

Will my recording have a watermark?

No. SwiftRec is completely free with no watermark, no trial timer, and no paid upgrade hiding behind it.

Do I need to sign in or create an account?

No. There is no account, no cloud upload, and no sign-in requirement. Everything records and saves locally on your computer.

Can I record both my microphone and what's playing on my speakers?

Yes. Toggle both the mic and speaker icons on in the toolbar before you press record. Both audio streams are mixed into a single track in the MP4.

What if the audio is out of sync or one track is louder than the other?

SwiftRec exports a standard MP4; if you need to adjust levels or sync audio after recording, you can open the file in any video editor. The recording itself is a straightforward mux of both audio sources.

Does it work on Windows 10?

Yes. SwiftRec runs on Windows 10 and Windows 11, both 64-bit, as long as .NET Framework 4.7.2 is installed (it comes pre-installed on both).

Will it slow down my game or application?

SwiftRec is lightweight and runs in the background. Performance impact is minimal, but it depends on your hardware and the resolution you're recording at.
