High-accuracy piano recording to MIDI
High-Accuracy Piano Recording to MIDI Converter
Upload an acoustic piano, digital piano, or phone recording and receive a standard MIDI file for a DAW or piano roll. MeluMimi follows the performance you recorded; it does not compose new music.
Guests can try 10 MIDI trial credits each month without signing in.
What the MIDI contains
The result stores detected piano notes, timing, note length, velocity, and optional sustain-pedal data. You can change sounds, move notes, quantize timing, or continue arranging in a compatible DAW or MIDI editor.
Which recordings work best
Use a clear solo-piano or piano-focused recording. Keep speech and other instruments quiet, avoid clipping, and reduce strong room echo. MeluMimi does not separate a piano part from a finished full mix.
Audio conversion or direct MIDI
For an acoustic piano or an audio-only performance, conversion recovers editable note data from the recording. If a digital piano can record MIDI directly, use that original MIDI instead because no audio recognition step is needed.
Choose the sustain behavior
Use With sustain for connected playing and pedal-heavy recordings. Use Without sustain when you need shorter note boundaries for detailed editing.
Common questions
Can I convert a piano recording to MIDI?
Yes. Upload WAV, MP3, FLAC, M4A, AAC, OGG, or WEBM audio up to 80MB, then download the detected performance as a standard MIDI file.
Does it work with a full band recording?
The service is designed for piano-focused recordings. Other instruments, vocals, and strong background noise can reduce transcription quality.
How accurate is piano recording to MIDI?
MeluMimi is optimized for high-accuracy piano transcription, including notes, timing, velocity, and optional sustain. No audio converter is exact for every recording: room echo, clipping, dense passages, and other sounds can reduce quality. Compare the result with your source and edit the MIDI when needed.
Does MIDI keep the original piano sound?
No. MIDI stores performance instructions, not the recorded piano tone. Playback depends on the virtual instrument or hardware sound source you choose.
