Make recorded music editable

What the converter does

Drop in an MP3, WAV, M4A, FLAC, OGG or supported video file and the converter estimates its notes, timing and dynamics. The result is a standard MIDI file you can edit in a DAW or notation app.

The transcription model runs locally in your browser. Conversion does not upload your source audio. Optional cloud audio backup requires your explicit selection. That privacy-first design also means the speed of a conversion depends partly on your device. AI arrangements are a separate cloud feature: sending audio for generation requires your upload consent.

Raw MIDI downloads are free. The optional Music Export Pack includes your edited MIDI, an automatic piano score draft in PDF and MusicXML, a labeled note-map image, original- and half-speed synthesized practice WAVs, a precise note list CSV and an export guide. You can listen and preview the draft before buying; the score uses a fixed tempo and a sixteenth-note grid and may need corrections.

No audio-to-MIDI system can perfectly separate every instrument in a dense mix. A clean vocal, lead, bass, piano or other isolated part usually gives a more workable result than a mastered song with several parts playing at once.

How we check the converter

Our conversion examples include original synthesized input audio, the notes used to generate it, and the actual Raw MIDI exported through this site's browser interface. We report missed and extra notes as well as useful results. These controlled signals help explain the tool; they are not a benchmark of real singers, acoustic instruments, or finished songs.

Our tutorials explain the actual conversion and editing workflow, with links to relevant documentation. If a step or statement is wrong, please send a correction.
