An MP3 to MIDI converter for solo melodies

Use this audio to MIDI tool to capture the pitch and timing of a clear melody as editable notes. The downloaded file contains note events, not the original recording or instrument sound.

How do I change MP3 to MIDI?

Choose your recording above, select Convert to MIDI, then preview the detected notes before downloading. To convert MP3 file to MIDI, your browser must be able to decode the file; if decoding fails, try a standard encoding.

What changes when I convert MP3 into MIDI?

The result is a single track of detected notes. Detection confidence controls which pitches are kept, minimum note length removes short fragments, and transpose shifts all detected pitches. These controls do not recreate the original tone.

Can I convert a song to MIDI?

A clear solo melody is the intended input. A full mix with chords, drums and several instruments can produce missing or incorrect notes. This tool does not separate a song into individual instrument tracks.

Is this an AI MP3 to MIDI tool?

No. This version uses local signal processing to estimate pitches, not a trained AI model. Your selected audio stays in your browser.

Is this the best MP3 to MIDI converter for my recording?

There is no best-for-every-recording claim here. Try a clear solo passage, listen to the note preview and compare it with your source. If you need chord recognition or instrument separation, this version does not provide those capabilities.

What goes wrong when converting MP3 to MIDI?

If you move beyond browser-based conversion to local tools like Basic Pitch, librosa, or Omnizart, you will hit version conflicts, silent failures, and quality issues that most tutorials skip. The MP3 to MIDI troubleshooting guide documents the specific errors, tested version combinations, and workarounds for each.

Does this tool also support WAV to MIDI?

Yes. This tool accepts both MP3 and WAV as input. For WAV to MIDI, choose a standard PCM WAV file — the browser decodes it locally, just like MP3, and the same pitch detection and note controls apply.

Can I convert voice to MIDI?

Yes, when the input is a clear recording of singing or humming — an unaccompanied single melody. Voice to MIDI uses the same pitch detection as instrument audio, so accompanying music, harmonies, or layered vocals will produce missing or incorrect notes.
