# Sound to MIDI

> Free online audio-to-MIDI converter. Drop an audio file and AI transcribes the notes into an editable MIDI file — powered by the open-source Basic Pitch model (Spotify), running 100% in your browser with no upload and no sign-up.

Everything runs on-device: audio is decoded and transcribed locally in the browser, so files are never uploaded. Output is a standard .mid file that opens in Ableton, FL Studio, Logic, GarageBand or MuseScore. Best results come from clean, isolated parts (piano, vocal, lead); dense full mixes are inherently harder for any audio-to-MIDI tool.
