Can you convert a song to MIDI?

Yes, but expect an editable transcription, not a finished copy of the song. Upload the audio to Midilace, convert it, then compare the downloaded MIDI with the recording in a MIDI editor. A full mix can produce missing notes, short fragments and notes from different parts on one track. Start with a short section if you need a particular melody.

ORIGINAL MIX TEST

What happened when two parts played together?

We built a 4.4-second, mono WAV at 22,050 samples per second: a sustained A3 bass under an A4–C5–E5–D5 lead. This is a controlled synthetic mix, not a recording of a complete song. On October 14, 2026, we converted that exact WAV with the public Midilace tool and inspected the downloaded MIDI.

The file contained 13 note events on one MIDI track. All five intended pitch names appeared, but the bass was broken into several events and the first two lead notes had short duplicate tails. Both input and output are available below so you can check the result yourself.

PRACTICAL WORKFLOW

How to get a useful MIDI draft from a song

  1. Choose a short passage. Select the verse, hook or phrase you actually need. A cleaner stem is easier to inspect than a full arrangement.
  2. Convert the audio. Midilace accepts MP3 and WAV plus the other formats listed on the tool page. The processing happens in your browser.
  3. Listen beside the MIDI. Load both into your editor. Check pitch, start time, duration and unwanted notes. MIDI does not retain the original singer or instrument sound.
  4. Repair the draft. Merge fragments of sustained notes, remove false attacks and move notes into separate tracks yourself if the arrangement needs it.
QUICK ANSWERS

Questions before you convert a song

Can I convert a complete MP3 song into MIDI?

You can submit an MP3, but a dense song is harder to transcribe accurately than a clear single instrument. Treat the output as a draft and check it by ear.

Will the result contain separate tracks for bass, drums and vocals?

Do not expect that from this tool. The two-part test above produced a single MIDI track even though the pitches of both parts were present.

Will converting the song to WAV first improve the notes?

Changing the file container alone does not reveal notes masked by other sounds. A clean stem or exposed phrase helps more than a format change.

Can I use the MIDI without editing?

Sometimes a simple passage is close enough for a sketch. In our controlled mix, note fragments remained even with only two parts, so inspect the file before using it in a project.
