Select STOP to finish. Preview your take in the result dialog.
Select Download to save the .webm file, or Delete to discard it.

What the recording captures

With the camera off, a take contains instrument audio plus the microphone if enabled. With the camera on, it also includes the live camera video.

The current recorder captures the camera stream directly. Hand overlays, interface controls and visual effects are not included in the exported video. There are no separate skeleton-only or aspect-ratio export controls.

Format and browser support

Downloads use WebM, rather than MP3, WAV or MP4. Recording requires browser support for MediaRecorder and the chosen WebM format. If recording fails, check the displayed error and try a compatible browser.

Sharing is offered when the browser supports it; Download saves the file directly. Recordings are assembled locally in the browser.

Recording questions

Do I need a camera to record music?

No. Use Keyboard Mode, play a sound and record with the camera off for an audio take.

Why will recording not start?

Play a sound to initialize audio and check that your browser supports WebM recording. For permission problems, see camera and browser help.

Can I record a theremin performance?

Yes. Open the online theremin, enable the camera and use the same REC and STOP controls.
