About

Developer platform from the makers of Moises. Jobs run workflows on your audio: vocal and accompaniment splits, instrument stems (bass, drums, guitars, keys, piano, strings, wind), lead and backing vocals, drum-kit pieces, plus chord, beat and lyric transcription. No monthly fee to start.

What you can do with it

Separate lead from backing vocals, or a drum kit into kick, snare, toms and cymbals
Build a karaoke or practice app with stems, chords and beats from one job
