Yes—you can turn an MP3 into a MIDI file here. Choose a clear vocal, piano, guitar or other single-instrument recording. The converter detects its notes locally in your browser and gives you a downloadable .mid file.
MP3 sound becomes note data—not another audio file.
An MP3 stores a recording. MIDI stores musical instructions: note pitch, start time, duration and velocity. This converter listens for those note events and writes them into a standard MIDI file you can edit, quantize, transpose or assign to a new instrument in a DAW.
Because the output describes notes rather than timbre, a converted guitar recording will not retain the guitar tone. Load the MIDI into a virtual instrument to choose its new sound.

QUESTIONS, ANSWERED
MP3 to MIDI FAQ
Can any MP3 be converted to MIDI?
The tool can analyze any MP3 your browser can decode, but accuracy depends on the recording. A clean melody, isolated vocal or single instrument is much easier to transcribe than a mastered song with drums, bass and harmony playing together.
Is this an MP3-to-sheet-music converter?
The immediate output is MIDI. The on-page score is a quick visual check, not publication-ready notation. For engraved sheet music, import the downloaded MIDI into notation software and correct the rhythm, key signature and spelling.
Will the MIDI match the original tempo?
Detected notes keep their timing in seconds. The tempo control writes project tempo metadata into the MIDI file. Set it to match your session before downloading, then fine-tune or quantize in your DAW.
Why are some notes missing or duplicated?
Low sensitivity can omit quiet notes; high sensitivity can capture overtones or noise. Increase the minimum note setting to remove short fragments, and use the cleanest isolated source available.
