Samplab
Edit audio notes like MIDI: polyphonic note editing, stem separation, and chord detection.
About
Samplab is an AI-powered audio editor that deconstructs polyphonic audio into editable notes, so producers can change pitches, fix sour notes, and rearrange chords the way they would edit a MIDI piano roll. It includes stem separation, automatic chord detection, audio warping, and audio-to-MIDI export, and ships as a VST3/AU plugin plus a standalone desktop app.
Its broader product family included Resynthesizer, an AI sample-to-synth instrument, and TextToSample, an offline text-to-sample generator built on Meta's MusicGen. Honest caveat: Samplab wound down its cloud service in September 2026 — cloud uploads stopped after September 17, 2026, so only the offline Resynthesizer path remains for eligible subscribers and past purchasers. This entry documents it as a historical landmark in AI audio editing rather than a live product.
