How Audio to MIDI Works
Choose a source and start transcription. When the MIDI is ready, download it and check the notes in your DAW.

AI detects notes
The model analyzes pitch, timing, and note events from the recording.

Save the MIDI file and continue editing it in production or notation tools.
What Is an Audio to MIDI Converter?
An audio to MIDI converter estimates the notes in a recording and writes them to a MIDI file. Your DAW can play those notes with a different instrument.
Try a clear vocal melody, piano phrase, guitar riff, or synth lead. A single lead is easier to check than a full mix.
Supported Audio Sources
- MP3 files
- WAV files
- M4A or MP4 audio
- OGG audio
- FLAC audio
Upload files up to 100MB, use a public direct audio URL, or choose a playable library track. A streaming-page link is not a direct audio file.
Who Uses Audio to MIDI?
Music Producers
Take a recorded phrase into the piano roll to build a new arrangement.
Songwriters
Hear a sung melody through an instrument and adjust the notes.
Composers
Use a musical sketch as a starting point for orchestration or notation.
Creators Using AI Music
Try transcribing a clear melody from generated audio, then correct it in your editor.
Choose a source you can check by ear
Start with one clear melody. Dense drums, layered voices, and overlapping instruments make note detection harder.
- Choose a short passage with one lead melody.
- Avoid heavy reverb, distortion, and loud background drums.
- Trim silence and unrelated sections.
- For a full mix, try an isolated stem before converting.
What Do You Get After Conversion?
Download a MIDI file with estimated note events. It tells your music software what to play; it is not a vocal stem or another audio mix.
Standard MIDI file
Import the .mid file into a compatible DAW or notation app.
Editable note data
Correct the notes, timing, and velocity in your editor.
No original sound baked in
Choose the instrument that will play the notes after import.
After importing the MIDI
Assign an instrument first, then compare the playback with your source.
Edit the notes
Remove extra notes and fix missed ones before adjusting timing or velocity.
Change the instrument
Try piano, synth, or another virtual instrument. The recorded tone is not stored in the file.
Build a new arrangement
Use the corrected phrase to build chords, a bass line, or another part.
Check the notes before building an arrangement
Transcription is less reliable with layered voices, wide pitch bends, distortion, and dense polyphonic passages.
Listen for extra notes, missed notes, and wrong start times. Correct those first; quantizing alone will not fix an incorrect melody.

It analyzes an audio file and creates a MIDI file that represents detected notes, timing, and pitch information. You can then edit that MIDI in a DAW or notation app.
Yes. You can upload MP3 files or paste a public direct MP3 URL. WAV, M4A, OGG, and FLAC are also supported.
It can process full audio, but the best results usually come from short clips with a clear melody or isolated instrument. Dense full mixes may need manual cleanup after conversion.
Yes. The result is a standard MIDI file that can be imported into most DAWs, notation tools, and virtual instrument workflows.
No. AI transcription is an estimate, especially with polyphonic audio, vocals, pitch bends, distortion, and layered mixes. Use the result as an editable draft.
No. The conversion runs from the browser through the web app, and the result downloads as a MIDI file.
No. MIDI stores note and performance data, not the original audio tone. After import, you choose the piano, synth, strings, or other instrument sound in your DAW.
For a dense mix, separating a clearer vocal or instrument stem may provide a better source to try. Conversion still estimates notes and timing, so review the MIDI manually. Separation outputs audio; conversion outputs MIDI.
