Record the screen and the sound coming out of it
Recording system audio in a browser is a permission, not a setting. Chrome and Edge expose the computer’s output as an audio track only when you tick “Share audio” in the screen picker — OneTake then mixes it with your microphone.

- Choose an audio mode“Mic + system” for narration plus the content, “System only” when you want a clean capture.
- Press “Start recording”The browser asks what to share.
- Tick “Share audio” in the pickerThis is a Chrome/Edge control, not ours. Without it you only get the microphone.
- Stop and check the metersThe VU meters in the panel show whether system audio actually arrived before you record.
Why system audio is a permission
A web page cannot open your sound card. The browser hands over the audio track only as part of a screen-share session you approved, and only if the platform supports it.
Chrome and Edge support it on Windows, macOS and ChromeOS for tabs and screens. Firefox currently does not expose system audio to `getDisplayMedia` at all.
Mic and system sound at the same time
OneTake routes both inputs through a local audio graph and records a single mixed track, so you get your voice and the video you are playing in one file, already balanced.
If the two sources fight, lower the system volume rather than shouting — the meters show both channels separately.
Frequently asked questions
Why is there no sound in my recording?
Almost always the “Share audio” checkbox in the picker. Chrome does not tick it by default.
Can I record system audio without a microphone?
Yes — choose “System only” and no microphone permission is requested.
Does Firefox work?
Firefox can record the screen but not the system audio track. Use Chrome, Edge or Safari for that.
Is the audio uploaded anywhere?
No. The mix happens in an AudioContext on your device and the result goes straight into the recording.
