Join thousands of musicians using AI to unlock their creativity
Music Demixer converts audio recordings into sheet music and MIDI files using a two-step AI process: first separating individual instruments from the mix, then transcribing each isolated part. This separation-first approach captures notes that traditional transcription tools often miss when trying to decode everything at once. Whether you're a musician learning complex pieces, a composer documenting your work, or an educator creating teaching materials, our technology delivers clean, accurate transcriptions you can trust.
When multiple instruments play simultaneously, their frequencies overlap and mask each other. A piano chord might hide a bass line, or drums might obscure a guitar riff. By separating instruments first using AI, we transcribe each part from a clean, isolated track - dramatically improving accuracy.
Our separation uses Meta's Demucs model (winner of the Sony Music Demixing Challenge), which understands the complex patterns that distinguish instruments even when they share similar frequencies. Combined with state-of-the-art transcription models for piano and drums, we deliver professional-grade results.
Our piano transcription achieves 96% note accuracy using state-of-the-art AI trained on thousands of hours of piano performances. It captures not just the notes, but also pedal movements (91% accuracy) and dynamics. This same research-grade technology powers professional music production software used by composers worldwide.
For drummers, we use advanced drum transcription that recognizes individual kit pieces - kick, snare, hi-hats, toms, and cymbals - converting them into both standard drum notation and MIDI. This level of detail is essential for music education and production.
Piano Students & Teachers: Learn songs by ear faster. Our AI isolates the piano part and converts it to accurate sheet music, showing exact fingerings and pedal markings. Teachers use it to create custom arrangements from any recording.
Composers & Arrangers: Document your ideas instantly. Hum a melody, play a progression, or import a reference track - get professional notation in MusicXML format that opens in Finale, Sibelius, or MuseScore.
Music Producers: Extract MIDI from any audio source. Sample a melody, recreate a bassline, or analyze chord progressions. Our separation technology ensures you're transcribing the exact part you want, not a muddy mix.
Beyond transcription, Music Demixer offers full stem separation for creating practice tracks, vocal removal for karaoke, and specialized tools for drums and bass.
Unlike cloud-based services with usage limits and upload queues, Music Demixer runs entirely in your browser. Your audio never leaves your device - process unreleased tracks, client work, or copyrighted material with complete privacy. No file size limits, no waiting for uploads, no monthly quotas.
This browser-based approach is our real innovation: unlimited songs powered by WebGPU acceleration. Process a 4-minute song in under 30 seconds, or work with full albums and long recordings. While competitors charge per minute or limit monthly usage, you get truly unlimited processing with your subscription.
What audio formats work best for transcription?
Music Demixer accepts all major formats: MP3, WAV, FLAC, M4A, and more. Higher quality inputs generally produce better transcriptions, but our AI handles compressed audio remarkably well. Outputs are available as MusicXML for notation software, MIDI for DAWs, and high-quality audio stems.
How accurate is AI music transcription?
Our piano transcription achieves 96% note accuracy on standard repertoire, with 91% pedal detection. Accuracy varies by instrument complexity and recording quality, but the separation-first approach consistently outperforms direct transcription methods, especially for dense arrangements.
Can it transcribe multiple instruments simultaneously?
Yes. The AI first separates each instrument, then transcribes them individually. You get separate tracks for piano, drums, bass, and other instruments, each with its own MIDI and notation. This is particularly valuable for educators creating practice materials or producers analyzing arrangements.
Free Plan: 3 transcriptions per month to test the technology. Ideal for occasional use or trying before subscribing.
Pro Plan ($9.99/month): Unlimited transcriptions, all quality settings, priority processing. Most users find the investment pays for itself with just one transcription job that would otherwise require manual work or expensive studio time.
3-Day Free Trial: Full access to test everything - piano transcription with pedals, drum kit separation, MIDI export, sheet music generation. No credit card required to start.
From piano teachers creating custom sheet music for students, to producers extracting MIDI from reference tracks, to composers documenting their ideas - thousands of musicians trust Music Demixer for accurate transcription. Our community grows by over 1,000 new users each month.
