Pick a clean source
Use a recording with one clear melody — a solo voice, a single instrument, or a hummed line. The cleaner the source, the more useful the notes. Drums, chords and busy mixes confuse a single-pitch detector.
How to convert MP3 to MIDI
You do not need software or an account. Here is the whole workflow, start to finish.
Open the converter
Go to the MP3 to MIDI converter and drop your file, or choose it. MP3, WAV, FLAC, OGG and M4A all work. Up to 50 MB or 5 minutes per file.
Convert and check
Select Convert to MIDI. The page decodes the audio on your device, follows the strongest stable pitch, and draws it as a piano roll. Review the detected notes before exporting.
Export the .mid
Download the MIDI file for your DAW, or copy the note list as tab-separated text with start time, length and velocity. The file keeps pitch, timing and estimated velocity — it does not keep the original sound.
GOOD TO KNOW
Common questions
Is this also a WAV to MIDI converter?
Yes. MP3 and WAV go through the same path. A clear mono melody gives the best result for either format.
Will it transcribe chords?
This converter tracks one dominant pitch at a time. For chords or full mixes, expect missing or partial notes. Slice the part you want first.
Does my audio leave my device?
No. Decoding, pitch detection and MIDI export all run in the page. There is no upload and no history.
What DAW can open the .mid?
Any standard MIDI player or DAW — GarageBand, Ableton Live, FL Studio, Logic, Reaper and most others read General MIDI files.
