Upload a track (MP3/WAV) — get a MIDI file with the transcribed notes: melody, chords, instrument line. Everything runs in your browser, nothing is uploaded.
💡 Best results on a solo fragment (one instrument or vocal). On a dense mix notes are approximate. Polyphony is supported.
Upload an MP3 or WAV track — the tool detects note pitch and duration with the Basic Pitch neural network and builds a MIDI file with pitch bends. The model is instrument-agnostic and polyphonic, so it works for melodies, chords and any instrument line. Everything is computed right in your browser — the audio never leaves your device.
Open the .mid in any DAW to edit it: change the instrument, fix notes, restyle it, or drop it into an arrangement. Great for lifting a melody from a reference, pulling a line out of a generated track, or quickly capturing a hummed idea.
