Audio to MIDI Converter

Your first conversion is free — no sign-up needed. Sign in for unlimited conversions.

Solo, clearly played instruments: voice, piano, guitar, and bass. Monophonic sources (a sung melody, a bassline) convert cleaner than polyphonic ones (piano chords, strummed guitar).

Real-time is capture: you sing or play into your mic and the tool listens live. Offline is precision: after you stop, the full neural pass analyzes the complete recording at once. Live monitoring guesses with no context; the offline pass hears the whole phrase — that's the version worth downloading.

Yes — the stem-aware pass splits a recording into vocal, drum, bass, and harmony stems so each is transcribed independently. It works best on reasonably clean mixes; a crushed, heavily limited master gives every separation engine a bad day.

For clean solo recordings, expect a solid draft — most users nudge a handful of notes afterward. For full songs and dense mixes, treat it as a starting sketch. Trim silence, use the clearest section, and keep reverb low for best results.

No — and that's the point. MIDI stores note data (pitch, timing, velocity), not audio. You play the result through your own virtual instruments: the notes from a recording, your sounds on top.

MP3, WAV, M4A, OGG, and FLAC. Voice memos from your phone work fine. If your recording lives in a video file, extract the audio first.

Yes. Fix timing, merge ghost notes, and quantize in the preview before downloading. For deeper edits, open the file in our free MIDI editor or any DAW.

No — the audio to MIDI converter runs entirely in your browser. Upload, record, preview, and download without installing software, and your first conversion needs no sign-up.

Yes — click any of the four examples above and the recording loads straight into the converter. They are real recordings in four formats: a ragtime piano solo (MP3), a vocal recording (WAV), an isolated harp part (OGG), and a saxophone-led jazz tune (M4A) — no upload needed. Four formats, four recordings — you can watch each one load and convert.

Check the piano-roll preview against the original audio before you download — inspecting it is free. Nudge slipped notes with the built-in quantize and merge tools, or open the file in our free MIDI editor for deeper fixes.

Give it the clearest signal you can. A solo voice, piano, guitar, or bass line converts cleaner than a full mix; trim silence, keep reverb low, and convert the clearest phrase first — most musicians only need 30 seconds anyway. When in doubt, convert the clearest phrase first and check the free preview before downloading.

Yes — that is a core use case. Press record and sing or hum straight into your browser, or drop in a phone voice memo. The engine is tuned for single-line vocal parts: one clear voice in, one accurate note stream out. Monophonic sources convert cleaner than full mixes.

Both — the free tier accepts up to 100MB or 5 minutes of audio. But shorter wins: most musicians convert the clearest 30-second phrase they're working on. A full dense mix comes out as a rough sketch that needs cleanup, while a clean solo clip lands close to finished.

Yes — just record again or drop in a better file. Each conversion is a separate task, and your first one is free, so experimenting costs nothing. For the cleanest result, re-record closer to the mic with less room reverb.
