Piano to MIDI Converter
AI-Powered · Optimized for solo piano timbre · 2 free trial credits on signup
Upload a piano recording and PureMIDI uses an AI audio transcription engine to detect pitch and timing, exporting a clean .mid file. Polyphonic-friendly — handles classical, jazz, and pop solo piano. Open the result directly in Logic, Ableton, FL Studio, or GarageBand, or import to MuseScore for automatic notation.
Upload audio
Choose a supported file, then convert it to MIDI.
Choose an audio file to start
Formats: MP3 / WAV / M4A / FLAC / OGG / WEBM / AAC. Max 12MB.
How it works
- 01
Upload your piano recording
Studio mics, digital piano DI, phone recordings, or acoustic piano captures all work. Drag and drop any audio file up to 12MB.
- 02
AI detects pitch and timing
The polyphonic engine handles chord progressions and two-handed playing. Solo piano recordings are most accurate.
- 03
Edit in your DAW or notation app
Download the .mid file and drop it into Logic, Ableton, FL Studio, GarageBand to swap sounds, or import to MuseScore / Dorico for automatic engraving.
Use cases
Capture improvisations
Turn a fresh improvisation into an editable MIDI draft instantly — never lose a song idea.
Transcribe piano solos
Convert jazz solos, classical pieces, and pop piano lines to MIDI for study, analysis, and rearrangement.
Layer with virtual instruments
Keep your original piano tone and double the part with synths, strings, or electric pianos using the same MIDI.
Auto-engrave to sheet music
Import the converted MIDI into MuseScore or Dorico for an automatic notation draft.
Piano recording accuracy notes
- Basic Pitch performs strongly on piano timbre. Solo piano recordings yield the highest accuracy.
- Digital piano DI or studio mic captures are the cleanest. Less room sound = better detection.
- Heavy sustain pedal blurs note boundaries; expect to tighten note lengths slightly in your DAW.
- Multi-piano recordings or full mixes with vocals/drums need stem separation upstream — isolate the piano stem first.
Recording setup vs accuracy
How you record directly determines MIDI accuracy.
| Recording method | Accuracy | Notes |
|---|---|---|
| Digital piano line out (DI) | ★★★★★ | Best — zero room sound |
| Studio mic (close) | ★★★★★ | Best in a treated room |
| Acoustic piano + room mic | ★★★★ | Recommended; some room tone |
| Digital piano + phone recording | ★★★ | Watch ambient noise |
| Live concert recording | ★★ | Audience noise, hall reverb |
| Full mix with vocals/drums | ★★ | Isolate piano stem first |
Practical tip
For the most accurate result, record your digital piano's line output directly. For acoustic piano, two mics placed close to the instrument give the cleanest results.
Frequently asked questions
Is the piano to MIDI converter free?+
Free trial — sign up for 2 free trial credits, valid 30 days. No subscription. Continue with one-time credit packs (no expiration); see /pricing for current packs.
Which piano recording formats are supported?+
MP3, WAV, M4A, FLAC, OGG, WEBM, and AAC. Maximum file size is 12MB on the free tier.
Does it detect chords and two-handed playing as polyphonic MIDI?+
Yes. The polyphonic engine handles chord progressions and two-handed playing. Very fast passages or heavy sustain pedal can blur note start/end times slightly — expect a quick cleanup in your DAW.
Is it good for classical piano analysis?+
Yes. Convert lossless WAV or FLAC solo piano recordings to MIDI, then import to MuseScore, Dorico, or Sibelius for pitch, rhythm, and dynamics analysis.
Can I convert MP3 piano recordings?+
Yes. 192 kbps or higher MP3 is recommended; lower bitrates degrade accuracy. Lossless WAV or FLAC is preferred when you have it.
Do you keep my piano audio?+
We only store files long enough to run the conversion, then clean them up. We never use your audio to train models.
Can I export the MIDI as sheet music?+
Yes. Open the .mid file in MuseScore, Dorico, Sibelius, or Finale and they will auto-engrave a notation draft you can refine.
Does it detect pedal information?+
The current engine detects only note pitch and timing — it does not extract sustain pedal CC64 events. To preserve a pedaled feel, manually lengthen note durations or add CC64 automation in your DAW.
