Open a MIDI file to adjust notes, listen, and export your changes.
Your next idea starts here
Open a MIDI file, or convert a recording first.
Standard MIDI (.mid, .midi) · up to 2 MB / 5,000 notesConvert a recordingBest with a single clear instrument. Dense mixes and drums need a different workflow.
For phones or low-memory devices, start with a clip under 30 seconds. Longer recordings can use substantial memory.
From a spark to a song
Three simple steps. A lot more room to create.
Find the notes
Basic Pitch analyzes pitch and timing right here in your browser.
Make it your own
Refine the notes, download a MIDI, and choose any sound in your DAW.
Less replaying. More creating.
A useful starting point for your next arrangement.
Editable from the first note
Adjust pitch, timing, length, and velocity in the built-in piano roll. Nothing is baked in.
Private by design
The model runs locally. Your recordings are never sent to an inference service or stored on our servers.
Take it anywhere
Export standard .mid files for Ableton Live, Logic Pro, FL Studio, GarageBand, and other MIDI-compatible tools.
A draft, with honest limits
Clear vocals, piano, guitar, bass, and synth lines work best. Expect to tidy up dense chords, reverb, and noisy recordings.
For the ideas you don’t want to lose
The hummed hook
Turn a voice memo into the beginning of a song.
The perfect riff
Try your guitar or bass line with an entirely new sound.
The practice session
See the notes and learn what you hear.
A few good questions
Is MP3 to MIDI free?
Yes. Conversion and editing run in your browser without a subscription, credits, or an account. We don’t charge for downloads.
What audio can I use?
Choose MP3, WAV, M4A, AAC, FLAC, OGG, or a browser recording. Decoding depends on your browser. Files must be below 20 MB and no longer than 3 minutes. WAV and MP3 are the safest choices.
Will it transcribe a complete song perfectly?
No automatic transcription is perfect. Basic Pitch works best with one pitched instrument at a time, including some chords. Dense mixes, drums, noise, and heavy effects are much harder. Use an isolated melody or stem for a cleaner draft.
Does MIDI sound like the original recording?
MIDI contains performance data, not recorded sound. Our preview uses a simple synthesized tone. Open the download on an instrument track in your DAW to choose the sound you want.
Are my recordings uploaded?
No. Audio decoding and transcription happen on your device. The page downloads the model files, then processes your recording locally. Refreshing the page clears the current session.
Why is the first conversion slower?
The first run loads the transcription model and starts the processing engine. Speed depends on clip length and your device. Keep the tab open; you can cancel at any time.
Can I change the notes?
Yes. Select notes to change pitch, start time, end time, and velocity. You can also transpose, quantize, delete, undo, and export. The separate editor also opens standard MIDI files.
Can I use the output commercially?
You are responsible for having the rights to your source recording and its composition. Converting a copyrighted song does not give you permission to reuse it. We don’t claim ownership of your audio or MIDI.
