Start with the clearest part
Choose a passage dominated by one instrument or voice. If drums, vocals, and accompaniment overlap, isolate the part you need before asking the MIDI converter to identify notes.

Audio input guide
From audio to MIDI: a practical guide
Match the converter to the source file before transcription. The tool on this homepage accepts .mp3, .m4a, and .flac; the WAV to MIDI tool accepts .wav, .mp3, .m4a, and .flac. Both create a downloadable .mid file in the browser.
Choose an audio to MIDI converter
Run the file through the matching converter and download the result. The output stores pitch, start time, and duration as editable events; it does not copy the original waveform.
Check splits, omissions, and timing
Open the .mid file in a piano roll. Merge short fragments that belong to one held note, restore a missing pitch, remove false detections, then set tempo and bar alignment before arranging.
Quick questions
What does audio to MIDI conversion produce?
Audio to MIDI conversion produces editable pitch, start-time, and duration events from a recording. On this homepage, an MP3, M4A, or FLAC goes in and a downloadable .mid file comes out; WAV input uses the separate WAV page.
Is audio into MIDI the same as exporting the original sound?
No. Audio into MIDI is a transcription: the browser estimates note events, so the result is a draft to check for short splits and missed notes rather than a copy of the waveform.
What about humming to MIDI or sing to MIDI?
The page can accept an MP3, M4A, or FLAC recording of a hum or sung take. It does not record from a microphone here, and it applies the same local audio transcription workflow to that file.
Is this a song to MIDI or music to MIDI converter?
It can process a song or music clip when the clip is supplied as an MP3, M4A, or FLAC file. Use a clear passage when you want the editable note draft to follow one part rather than the full mix.
Measured check: the same four-second phrase was converted from WAV and MP3 on the live site. Each run found all four source pitches and produced five note events: four long notes and one short split note. Each downloaded MIDI was 93 bytes.
