MP3 to MIDI

Drop one file. It is decoded and transcribed in this tab, then a standard .mid file is ready to download.

Conversion starts as soon as you choose a file. Clear recordings led by one instrument or voice usually produce a more useful draft than dense mixes or drums.

What you can bring in

The page asks your browser to decode the file. Format names below describe accepted file extensions, not a promise that every browser and codec combination can decode them. A ten-minute 22.05 kHz mono float32 analysis buffer uses about 53 MB of memory.

Your recording stays on this device

The browser reads the file into memory. A bundled note model estimates pitches, starts, lengths and velocities here in the tab. The generated download is assembled locally.

  1. 01
    Decode

    Your browser opens the file and mixes its channels for analysis.

  2. 02
    Transcribe

    The bundled note model estimates editable note events.

  3. 03

    The page writes those events into a standard MIDI file.

03 / FAQ

Straight answers

Audio and MIDI are different kinds of data, so this is transcription—not a lossless format change.

How do I convert an MP3 file to MIDI?

Drop the MP3 above. The change from MP3 to MIDI starts immediately, and the download button appears when note transcription finishes.

Can I convert audio to MIDI without uploading it?

Yes. Decoding, model inference and MIDI writing happen in this browser tab. The selected file is not sent to a server.

What should I expect from the result?

Treat it as an editable draft. Solo piano, guitar, bass, voice or a hummed melody are more suitable than percussion, heavy reverb or a full mixed song. Check the notes in a DAW or notation app.

Can I convert MIDI to MP3 here?

Yes. Switch direction above and drop a .mid file. This page renders it with a simple built-in synth, then encodes the result as MP3 on your device.

Why can a listed format still fail?

Containers and codecs are separate. For example, two MOV files can carry different audio codecs. If this browser cannot decode the audio track, the page reports that specific problem.
