What is MP3 to piano MIDI?
MP3 to piano MIDI transcribes a recording into MIDI tuned for solo piano — melody and chords laid out as notes on a single keyboard part. It is built for piano covers, tutorials, and practice, where you want playable notation rather than a scattered multi-instrument guess.
The model detects the pitches in your MP3 and normalizes them into piano-friendly voicing, so the result opens cleanly in a DAW or notation editor. Preview it on the roll, fix any stray notes, and export MIDI or sheet music to learn or perform the piece.
How it works
Upload your piano audio
Drop an MP3 or WAV of a piano recording. Cleaner, single-instrument piano audio transcribes most accurately. No account needed to convert and preview.
Preview on the piano roll
The result is merged into one Acoustic Grand Piano track and gently aligned to the detected beat. Compare it to the original, then adjust sensitivity or minimum note length if needed.
Download MIDI or sheet music
Download the piano MIDI, correct notes directly on the roll, or export MusicXML/PDF sheet music for MuseScore, Sibelius, or printing.

Highlights
Piano-tuned output
Detection is normalized for a single piano part, not a scattered multi-track result.
Practice-ready notation
Export MusicXML/PDF to read, print, and learn the piece at the keyboard.
Editable roll
Correct chords and melody note-by-note before you export.
Getting a clean piano transcription
- Solo piano recordings work best. Backing tracks, vocals, or drums over the piano will add notes that are not part of the piano part.
- Dense chords and fast runs are the hardest to detect perfectly — expect to touch up a few notes in the editor.
- If the sustain pedal blurs notes together, raising the minimum note length can help separate them.
- AI transcription gives you a fast draft; fixing a handful of notes beats transcribing the whole piece by hand.
Frequently asked questions
How do I convert an MP3 piano recording to MIDI?
Upload the MP3 or WAV of your piano recording — up to 50 MB and roughly 10 minutes — and it runs through the same Basic Pitch transcription used everywhere on this site, then a server-side piano post-processing pass that merges the detected notes into one Acoustic Grand Piano track and gently aligns them to the detected beat, which is what sets this page apart from the general audio-to-MIDI converter. The result lands on an interactive piano roll where you can play it back against the original recording, adjust detection sensitivity or minimum note length, and re-transcribe the same upload without submitting it again. Once it looks right, download the piano MIDI directly with no account required — no separate software to install at any point, and the same upload can be re-transcribed with different settings as many times as you need.
Does it work for chords, not just single melodies?
Yes — chords and full polyphony are detected, not just single-note melodies, since real piano playing is rarely just one note at a time. That said, accuracy still scales with how much is actually happening at once: a single melodic line remains the most reliably accurate case, simple triads and block chords come through quite well, and dense, fast passages with a lot of simultaneous voices — thick left-hand accompaniment under a busy right-hand run, for instance — are where you're most likely to see a few misdetected or missing notes. None of that is a hard failure, though; it just means denser passages are exactly where the built-in piano-roll editor earns its keep, letting you fix the handful of notes that came through wrong rather than re-transcribing the whole piece by hand from scratch.
Is the MP3 to piano MIDI converter free?
Yes — conversion and browser preview are completely free with no account required at any point. Upload your piano recording, watch it merge into a single piano track on the roll, and listen back against the original immediately, all without signing up for anything. What requires an account is what comes after that: your results persist in a conversion history instead of disappearing when you close the tab, the full note-editing toolkit (move, delete, transpose individual notes) becomes available rather than just previewing, and you unlock exporting the piece as MusicXML or PDF sheet music alongside the plain MIDI file — useful specifically for piano transcriptions people often want to actually read and play from rather than just listen back to on a device, whether for practice or for teaching.
Can I get sheet music from the piano MIDI?
Yes — once signed in, you can export any piano transcription as MusicXML, which opens in notation software such as MuseScore, Sibelius, or Finale for further editing, or as a PDF ready to print or read directly at the keyboard. This is one of the more useful export paths on the whole site precisely because the source material here is already normalized into a single piano part rather than scattered across multiple instrument guesses, so the resulting notation tends to be cleaner and more immediately playable than sheet music generated from a denser multi-instrument transcription. As always, review the notes on the piano roll and fix anything that looks wrong before exporting, since whatever the MIDI contains at export time is exactly what gets engraved into the score, with nothing corrected automatically at the export step itself.
