Lossless piano WAV to MIDI
High-Accuracy WAV to MIDI Converter for Piano
Upload a clear piano WAV and turn the performance into editable MIDI notes for a DAW or piano roll. Keep the original WAV: MIDI stores the recognized performance data, not the recorded piano sound.
Guests can try the converter without signing in. Upload only recordings you may process.
Use the original WAV
A WAV can preserve the recording without lossy compression. Upload the clean original when you have it; converting it to MP3 first cannot add note information and may remove useful detail.
Lossless does not fix a noisy recording
WAV is a file format, not a guarantee of accurate transcription. Clipping, room echo, speech, drums, and other instruments can still hide piano note boundaries. Piano-only or piano-focused recordings work best.
Prefer direct MIDI when available
If a digital piano can record MIDI directly, use that MIDI as the first choice because it already contains key, timing, velocity, and pedal events. Audio transcription is useful when you have only a WAV recording.
Common questions
Do I need to convert WAV to MP3 first?
No. MeluMimi accepts WAV directly, so keep the highest-quality authorized source instead of adding an unnecessary compression step.
Does WAV produce the original piano sound in MIDI?
No. MIDI contains performance events. Its playback sound comes from the virtual instrument or hardware used after conversion.
What is the WAV upload limit?
Each file can be up to 80MB. The processable duration also depends on the remaining guest or account allowance.
