What Is MP3 to MIDI Conversion?
Turn Any MP3 Into Editable MIDI Notes
MP3 to MIDI conversion is the process of analyzing an audio recording and extracting each individual note as editable MIDI data. You upload a song or recording in MP3 format, and the tool identifies pitches, timing, velocity, and chord structures. The output is a standard .mid file that opens in any DAW or notation software. Most desktop tools for MP3 to MIDI cost money and require installation. Old shareware converters produce garbled results with dense mixes. This tool runs in your browser, uses a neural network trained on thousands of multi-track recordings, and handles polyphonic audio that trips up simpler converters. Solo instruments convert with near-perfect accuracy. Piano, guitar, bass, and vocal melodies all come through clean. Full band recordings work too, though you may want to isolate stems first using our vocal remover for the best note separation.
Fast MP3 to MIDI Processing
Most MP3 to MIDI conversions finish in 30 to 60 seconds. A four-minute track gives you a usable MIDI file before you finish your coffee.
Accurate Note Detection
Each note in your MP3 gets identified by pitch, start time, duration, and velocity. Solo piano and guitar recordings produce MIDI with over 90% accuracy on clean takes.
Polyphonic Chord Recognition
When you convert MP3 to MIDI, chords land as stacked notes with correct voicings. The tool handles dense jazz chords and sustained pads that simpler converters miss entirely.
Automatic Tempo Detection
The converter reads BPM from your MP3 and maps it to the MIDI file. Your project stays in time when you import the .mid into a session.
Runs in Your Browser
No desktop software to download. No plugin to configure. Upload your MP3, wait for the conversion, download the MIDI file. Done in three clicks.
Standard .mid Output
Every MP3 to MIDI conversion outputs a standard .mid file. Opens in Ableton Live, FL Studio, Logic Pro, GarageBand, MuseScore, Finale, Sibelius, or any music software you already use.
For Learning Songs
MP3 to MIDI for Song Transcription
See every note on screen instead of guessing by ear
Heard a piano riff you want to learn? Run it through the MP3 to MIDI converter and open the result in your DAW or MuseScore. Every note shows up on a piano roll with correct timing and velocity. Music students and teachers use MP3 to MIDI transcription daily to break down songs in minutes instead of hours of rewinding.
For Music Production
Turn Any MP3 Into an Editable MIDI Project
Rebuild tracks note by note in your DAW
Got a reference track as an MP3? Run MP3 to MIDI conversion and drop the result into your session. Swap the piano for strings, shift the key up two semitones, double the tempo for a remix. Producers convert MP3 to MIDI to pull chord progressions from records they admire and build original arrangements on top.

MP3 to MIDI Converter FAQ
Everything You Need to Know
You upload an MP3 file and the converter runs it through a neural network that identifies individual notes, chords, and rhythms in the audio. It outputs a standard .mid file containing MIDI events for every detected note. The whole process takes 30 to 60 seconds for a typical song. No manual transcription needed — the AI does the listening for you.
Solo instruments and clean recordings produce highly accurate MP3 to MIDI results — typically above 90% for piano and guitar. Dense mixes with drums, bass, and multiple instruments playing at once are harder. For best results on full band recordings, isolate individual stems with our vocal remover first, then convert each stem from MP3 to MIDI separately.
Yes — completely free, with no credits, no account, and no upload limit on the number of conversions. The MP3 to MIDI conversion runs entirely inside your browser using the Basic Pitch note-detection model, so there is no server cost to pass on. You can convert as many files as you want without signing in.
Besides MP3 to MIDI, the converter accepts WAV, OGG, FLAC, and M4A files up to 50MB each. WAV and FLAC often produce slightly better MIDI output because they are uncompressed and keep more of the attack detail the note detector relies on.
Any DAW opens the .mid files from MP3 to MIDI conversion: Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, and Reaper. For sheet music, use MuseScore, Finale, or Sibelius. MIDI is a universal format supported by every music application since 1983.
No — and that is the point. MIDI stores note data, not audio. When you convert MP3 to MIDI, you get the notes, timing, and velocity from the recording, but not the actual sound. You choose which instruments to assign in your DAW. This is what makes MIDI useful: you can take a guitar recording and play those same notes back as piano, strings, or synth.
No. The MP3 to MIDI conversion happens entirely in your browser — the audio is decoded and analysed on your own device, and the file is never sent to a server. Most online MP3 to MIDI converters upload your audio for server-side processing; this one does not, which is why it works without an account and why unreleased or client work stays private.
The note detector analyses one mono signal at 22,050 Hz. A stereo file is downmixed to mono before analysis, so instruments that overlap in pitch — a full mix with drums, bass, vocals, and guitar at once — end up competing for the same notes. A solo piano, guitar, flute, or vocal line has nothing to compete with, which is why those convert cleanly. For a full song, isolate a stem first and convert that stem to MIDI.
