How accurate is the conversion?

Our AI achieves 99.4% note detection accuracy on clean, single-instrument recordings. The system uses Spotify's Basic Pitch neural network trained on tens of thousands of hours of music. For best results, use recordings with a single instrument and minimal background noise.

Is my audio uploaded to a server?

No. All audio processing happens directly in your browser using WebAssembly. Your files never leave your device. The AI model runs locally — even your internet connection doesn't matter once the page loads.

What file formats can I upload?

We support MP3, WAV, FLAC, OGG, M4A, AAC, AIFF, WMA, and Opus.

Can I use the MIDI commercially?

Yes. The MIDI files you download are yours to use however you want — in commercial releases, remixes, live performances, or educational materials. No attribution required.

What DAWs does the MIDI work with?

Compatible with Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, Reaper, Pro Tools, Studio One, and any software that supports standard MIDI files.

Is there a file size limit?

We support files up to 50MB, which covers most audio files up to 60 minutes of high-quality audio.

Does it work on mobile?

Yes, the converter works on mobile browsers. For the best experience with larger files, we recommend using a desktop browser.

WHAT IS MIDI

MIDI is the universal language of digital music.

MIDI(Musical Instrument Digital Interface) is a technical standard that lets musical instruments, computers, and other devices communicate. Unlike audio files (MP3, WAV), MIDI doesn't contain sound — it stores performance data: which notes were played, when, how hard, and for how long.

This makes MIDI files incredibly small (typically under 100KB), fully editable (change notes, tempo, instrument), and universally compatible with every DAW — Ableton Live, FL Studio, Logic Pro, GarageBand, Cubase, and more.

MP3 / WAVContains recorded audio waveformLarge file (3-10 MB per minute)Cannot edit individual notes

MIDIContains note/performance dataTiny file (under 100KB)Fully editable in any DAW

What is MIDI used for?

Music production — Write, arrange, and produce songs in DAWs
Remixing — Extract melodies and chord progressions from songs
Learning — Study note patterns and song structures
Live performance — Control synthesizers and virtual instruments
Transcription — Convert recordings into editable sheet music
Game audio — Create adaptive soundtracks that respond to gameplay
