Find a duet partner

Singmeister matches singers from a 30-second onboarding clip. CREPE, Parselmouth, and Essentia estimate pitch, tempo, key, and melody. Those musical features are stored. Raw audio and voiceprints are not.

The analysis service keeps Essentia in its own process. The browser never talks to it directly.

Shotstack stitches the duet. FFmpeg is a fallback stub and stays off unless Shotstack is unset and the fallback flag is on.

A monthly subscription is required to sing and match. Watching a finished duet is free.

Use a 16-bit PCM WAV from 25 to 30 seconds. Singmeister stores pitch, tempo, key, and melody. The raw audio is not written to Supabase.
