Audio to MIDI Converter

Point this tab at a hummed line or a short clip. It writes MIDI notes here, then you can save the .mid or jump to the piano roll.

This tab does the work. There is no account, no credit meter, and no copy of your audio on our servers.

Turn a recorded melody into MIDI notes

From a take to a .mid in this tab

Short, dry, one part. If the clip sounds like a finished mix, skip this tool.

  1. 01

    Drop a clip or use the mic

    An MP3, a WAV, or a few bars recorded here. Cut the silence at both ends.

  2. 02

    Let the tab write MIDI

    Pitch onsets become notes in a standard .mid. That file is built locally.

  3. 03

    Save it or open the grid

    Download if the pass is close enough. Otherwise send it to the piano roll.

What the converter hears, and what it misses

It follows one pitch line. A dry vocal or a single guitar part lands. A mastered song with drums does not.

Give it one part

Hum, whistle, a lead guitar, a bass, or a right-hand piano line. Mute the band before you convert.

Expect to nudge the grid

Octave hops and early onsets show up. That is why the piano roll sits next to the download.

Before you convert

Can I convert MP3 to MIDI in the browser?

Yes. Drop MP3, WAV, FLAC, OGG, M4A, AAC, or WebM. The work happens in this tab.

What audio works best?

One dry melody. Voice, piano, guitar, or bass. A full mix with drums and reverb will smear the grid.

Does this upload my audio?

No. We do not store the clip, charge credits, or keep a conversion history.

Can I edit the MIDI after conversion?

Yes. Save the .mid, or open the piano roll from the result and move notes there.

Map a take onto MIDI notes

Drop a dry clip, let this tab write the .mid, then open the piano roll only if the grid needs a pass.
