What is WAV to MIDI?
WAV to MIDI converts an uncompressed audio recording into editable MIDI notes. Because WAV keeps the full, lossless waveform — no MP3 compression artifacts — it is an ideal source for transcription: the pitch-detection model gets the cleanest possible signal to read notes from.
The output is a MIDI file describing the performance rather than the sound, so you can reopen it in a DAW or notation editor to transpose, quantize, re-instrument, or print it. Preview the notes on the piano roll and correct anything the model missed before you export.
How it works
Upload your WAV file
Drop a WAV recording — lossless audio gives the transcription the cleanest signal to work from. MP3 is supported too. No account needed to convert and preview.
Preview and fine-tune
Listen to the transcription on an interactive piano roll, compare it against the original WAV, and adjust detection sensitivity, minimum note length, or pitch bends to re-transcribe.
Download MIDI or sheet music
Download the MIDI file, correct wrong notes directly on the roll, or export sheet music as MusicXML/PDF for MuseScore, Sibelius, or printing.

Getting the cleanest transcription from WAV
- WAV is lossless, so it avoids the compression artifacts that can confuse detection in low-bitrate MP3s — start from WAV whenever you have it.
- Monophonic sources (a single melody line — vocals, flute, lead guitar) transcribe far more accurately than dense mixes.
- Trim intros, applause, and silence before uploading — cleaner input means fewer ghost notes.
- If you hear extra notes, lower the detection sensitivity; if soft notes are missing, raise it and re-transcribe.
Frequently asked questions
How do I convert WAV to MIDI?
Upload your WAV file, let the transcription run, then preview it on the piano roll. You can fine-tune detection and export the result as a MIDI file — no software to install.
Is WAV better than MP3 for transcription?
Usually, yes. WAV is uncompressed, so it preserves detail that lossy MP3 encoding can smear. Both are supported, but if you have the original WAV, use it.
Is this WAV to MIDI converter free?
Yes. You can convert and preview WAV to MIDI online for free without creating an account. Signing in additionally saves results to your history and unlocks editing and sheet music export.
What is the maximum file size?
Uploads up to 50 MB. For best results use dry, monophonic recordings — a single melodic line without heavy accompaniment.
