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.

Why use it

MP3 to MIDI without a cloud project

Drop an MP3, WAV, or a hummed line and the clip never leaves the tab. You get notes you can move, not another hosted session.

Clips this page will read

MP3 and WAV are the usual drop. This MP3 to MIDI converter also reads FLAC, OGG, M4A, AAC, and WebM, as long as the file is under 50 MB and five minutes.

Jump straight into the grid

If a note sits off the beat, open the piano roll from the result instead of running the conversion again.

No account in the way

There is no credit meter and no library row for this converter. Export if you want a copy that survives closing the tab.

Use cases

When audio to MIDI is the right first step

Use it when the idea already exists as sound and you need pitches you can rearrange in a DAW.

Beat sketches

Hum a hook, convert it, then assign a synth in your DAW instead of rebuilding the melody by ear.

Practice takes

Turn a piano or guitar take into notes and slow the line down by editing the MIDI instead of stretching the audio.

Voice memos

Keep a hummed chorus as notes so the next session starts from pitches, not a phone recording.

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, run the stem splitter first.

  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 for a cleaner grid.

  2. 02

    Let the tab write MIDI

    Pitch onsets become notes in a standard .mid. That file is built locally, in this browser tab.

  3. 03

    Save it or open the grid

    Download if the pass is close enough. Otherwise send it to the MIDI editor and fix the notes by hand.

What the converter hears, and what it misses

It follows one pitch line. A dry vocal, a piano line, 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 audio to MIDI.

Expect to nudge the grid

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

MP3, WAV, or a live take

The same converter handles a file from disk and a few bars recorded with the mic. Both write a standard .mid you can open anywhere.

Song to MIDI, one part at a time

A full song needs a stop first. Run the stem splitter, keep the vocal or the piano, then convert that single layer into notes.

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.

Can I convert WAV to MIDI too?

Yes. WAV, MP3, FLAC, OGG, M4A, AAC, and WebM all work. The format matters less than how clean the single part sounds.

Does it work on a full song?

Not well. This converter follows one pitch line, so drums and a full mix smear the grid. Run the stem splitter first and convert one isolated part.

Can I convert a piano recording to MIDI?

Yes. A single piano line or a right-hand part converts best. Dense chords and pedal noise can add extra notes you will want to clean up.

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 audio to MIDI converter write the .mid, then open the piano roll only if the grid needs a pass.
