On-device AI audio

On-device AI stem separation & instrument performance

QV1 splits a song into vocals, drums, bass, and accompaniment on your computer — a stem splitter and vocal remover that keeps source audio on your machine. Neyora turns text, a hummed melody, or MIDI into an instrument performance with DDSP. Free audio, PDF, and image tools run in the browser as well.

Neyora

Classic samplers play back recordings. Pure neural vocoders often smear pitch and lose editability. DDSP sits between them: the network estimates musical controls, then a differentiable synth renders tone you can still reason about — breath, bow, reed, room. Neyora uses that idea for solo instrument performance from text, voice, or MIDI.
