MP3 to MIDI Converter

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

For clean single-instrument audio — solo piano, a vocal line, a guitar riff — note detection is strong enough to use with light cleanup. For dense full-song mixes, expect a rough draft that needs fixing in your DAW or our free midi editor.

MP3 is the primary input; WAV, FLAC, and OGG also work. Output is always a standard .mid file that any DAW or notation app opens. For video sources, extract the audio first.

No — and that is the point. MIDI stores note data (pitch, timing, velocity), not audio. You lose the original tone but gain full editability: swap instruments, fix notes, or print sheet music.

No — transcription runs entirely in your browser. Your files never leave your device.

100MB or 5 minutes of audio on the free tier. Longer file? Trim it to the phrase you are actually working on — most musicians only need 30 seconds anyway.

Any DAW — Ableton Live, Logic Pro, FL Studio, Cubase, Reaper, GarageBand — plus notation apps like MuseScore and Sibelius. Import the .mid and assign any virtual instrument to each track.

That is the whole point of MIDI. Fix wrong notes, quantize timing, or split tracks in our free online midi editor — or import into your DAW. Most users spend a few minutes cleaning up.

No — the mp3 to midi converter runs entirely in your browser. Upload, convert, 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: a Chopin piano étude, an Eccles violin sonata, a classical guitar piece, and a Debussy flute solo — no upload needed. Each card shows the real format and the measured length — the file that loads is exactly what the card describes.

Check the piano-roll preview before you download — inspecting it is free. Fix slipped notes in our free MIDI editor, or import the file into your DAW and quantize there. Clean solo recordings need the least cleanup; dense mixes need the most. Most users spend a few minutes cleaning up — that is normal, not a failure of the conversion.

Start with the cleanest recording you have. Solo instruments beat full mixes, monophonic lines beat dense chords, and less reverb means fewer ghost notes. Trim silence and convert the clearest phrase first — most musicians only need 30 seconds anyway. When in doubt, convert the clearest 30 seconds first and check the preview — inspecting it is free.

Yes — voice memos, humming, and sung melodies are core use cases for this mp3 to midi converter. The engine is tuned for single-line vocal parts: one clear voice goes in, one accurate note stream comes out, with no ghost notes from background hiss. A phone voice memo works fine as long as the melody is clear.

Yes. The engine maps timing to a tempo grid during transcription, so the MIDI plays back at the speed of your recording — not at some default tempo. Key signature exports with the file too, so the transcription lands in your DAW musically intact, ready for a virtual instrument.

Yes — nothing stops you from running the same file through different transcription modes. Try Piano mode for the keyboard part and Melody mode for the vocal line, then keep the cleaner take. Each conversion counts as a separate task against your free quota.
