What Is an Audio to MIDI Converter?
An audio to MIDI converter turns a recorded melody or musical phrase into a standard MIDI file that can be edited in a DAW or notation app. It estimates notes, timing, and pitch from audio instead of creating another audio recording.
Use it for melodic source material such as a vocal idea, guitar riff, piano sketch, synth lead, or AI-generated audio clip when you want an editable musical starting point.
Supported Audio Sources
- MP3 files
- WAV files
- M4A or MP4 audio
- OGG audio
- FLAC audio
Upload local MP3, WAV, M4A, OGG, or FLAC files up to 100MB, paste a public direct audio URL, or select a track from My Songs when it has a playable audio URL.
Who Uses Audio to MIDI?
Music Producers
Turn recorded loops, hooks, and AI-generated ideas into editable MIDI parts for arrangement, sound design, and remixing.
Songwriters
Capture a sung or played melody and move it into a piano roll where you can refine the notes and build chords around it.
Composers
Convert musical sketches into MIDI so they can be orchestrated, notated, or expanded inside composition software.
Creators Using AI Music
Extract a MIDI draft from generated audio and reuse the melodic idea in a cleaner, more controllable production workflow.
How to Get Better MIDI Transcriptions
Audio-to-MIDI works best when the musical idea is clear. Clean monophonic melodies, piano riffs, guitar lines, and synth leads are easier to transcribe than dense full mixes.
- Use short clips with one clear lead melody or riff.
- Avoid heavy reverb, distortion, crowd noise, or loud background drums.
- Trim silence and unrelated sections before converting.
- For full songs, convert the clearest melody section first, then edit the result in your DAW.
What Do You Get After Conversion?
The output is a downloadable MIDI file, not a new mixed audio track. MIDI stores performance instructions that your music software can replay with different instruments.
Standard MIDI file
Download a .mid file that can be imported into most DAWs, notation apps, and virtual instrument workflows.
Editable note data
Use the MIDI to adjust notes, timing, velocity, quantization, and arrangement details after transcription.
No original sound baked in
MIDI does not preserve the original vocal, guitar, or synth tone. Assign your own instrument sound after import.
Where MIDI Fits in Your Workflow
The generated MIDI file is a starting point, not a finished master. Once downloaded, you can load it into production and notation tools for deeper editing.
Edit the notes
Clean up timing, remove wrong notes, adjust velocity, and quantize the performance inside your DAW.
Change the instrument
Assign the MIDI to piano, synth, strings, bass, or any virtual instrument instead of keeping the original audio sound.
Build a new arrangement
Use the converted melody as the seed for chords, counter-melodies, harmonies, or a full production.
Audio to MIDI Accuracy
AI transcription is an estimate. It is less reliable with dense mixes, drum-heavy tracks, layered vocals, wide pitch bends, and complex polyphonic passages.
For best results, treat the MIDI as an editable draft. Review it in your DAW, then correct the notes, timing, and velocities that matter for your production.

Create MusicFrequently Asked Questions
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.
