Best with one voice or instrument. Try a 15–30-second phrase.

File support & processing time

A short clip may take 30 seconds–2 minutes; longer audio can take several minutes or more. Device speed and the first model download affect timing.

MP4/WebM need a browser-readable audio track. If a video will not open, export MP3 or WAV. For files over 100 MB, shorten the recording or extract its audio.

Profiles adjust detection, pitch bends and cleanup. You can fine-tune them in Advanced settings.

Or record a solo voice or instrument · up to 60 seconds.
