Windows audio guide
Record your Windows screen with the sound you need.
A screen-sharing permission is not an audio guarantee. Choose the source, enable audio in the browser chooser, then check what the browser actually returned.
Start with a tab for a browser video or demo
- Open the content you want to record in another tab. Use desktop Chrome or Edge as a practical starting point for tab audio.
- In the recorder, select Tab and leave Shared sound on. Turn on Microphone only if you want your voice.
- Click Choose screen. In the browser chooser, select your content tab and enable its audio checkbox, often called Share audio. Labels vary by browser version.
- Start playing sound in that tab. Speak if Microphone is on. The recorder runs a five-second check and shows a separate meter for each source.
- Start recording only when the returned tracks and levels match your intention. Pause, resume, then choose Stop & save to finish.
Connected is not the same as audible. A returned audio track can still contain silence. Watch the level meter while the chosen source is playing.
Recording an app window or your entire screen
Select Window or Screen here, then make the final choice in the native browser chooser. The selection here is a hint, not a restriction. System audio options depend on your browser, Windows version and selected source; a window selection may return no audio at all.
If you need sound from an app, review the chooser’s available audio options. If shared audio is absent, the recorder reports No track rather than pretending the app sound is captured. A microphone adds narration, but it does not turn into a digital system-audio track.
Keep the check useful
The five-second check does not produce a saved recording. It previews the source and measures audio. If no sound is detected, play audio and choose Recheck sound. If a track is missing, cancel setup and choose the source again with audio enabled. You can explicitly continue without detected sound when a silent recording is intentional.
The meters show each input before mixing. They help find an audio problem; they do not promise a final sound quality or volume. Check the finished local preview before sharing the downloaded file.
Browser permissions and files
The website requests screen sharing only after your click and microphone permission only if you selected Microphone. It does not request a camera. Your browser decides which sources and audio tracks are available. Recording stays local and ends if you stop sharing.
MP4 is available only if your browser can encode it. Otherwise the output is WebM. See the format guide and recording limits before a long session.
Technical reference: MDN’s screen capture API documentation explains why returned audio varies and why a browser chooser is required.
