Join thousands of musicians using AI to unlock their creativity
Music Demixer is the most accurate AI music transcription tool available, converting any audio recording into professional sheet music and editable MIDI files. Our unique approach first separates instruments using advanced AI, then transcribes each part individually for unmatched accuracy. Whether you're a musician learning complex pieces, a composer documenting your work, or an educator teaching music theory, our transcription technology delivers studio-quality results that traditional tools simply cannot match.
Traditional transcription tools try to identify notes from mixed audio where multiple instruments play simultaneously, often leading to errors and missed notes. Our breakthrough approach first separates each instrument using advanced AI, then transcribes the isolated parts individually. This means we can accurately capture that quiet bass line hidden behind drums, or the subtle piano harmonies masked by vocals.
Our separation technology uses deep neural networks trained on thousands of hours of professionally mixed music, understanding the complex patterns that distinguish a guitar from a piano, or vocals from drums, even when they occupy similar frequency ranges. This clean separation is the foundation that makes our transcription results so remarkably accurate.
We use the Demucs Hybrid Transformer model, winner of the Sony Music Demixing Challenge. This isn't just marketing speak — it means our stem separator consistently outperforms alternatives in blind listening tests. The model combines:
This sophisticated approach is why we can cleanly separate overlapping instruments like bass guitar and kick drum, or extract vocals from dense arrangements without artifacts.
Audio to Sheet Music: Convert any recording into professional notation in MusicXML format. Perfect for music educators, students learning complex pieces, composers documenting their work, or musicians who want to see exactly what they're hearing in traditional notation.
Audio to MIDI Conversion: Transform audio into editable MIDI files for digital music production. Ideal for producers who want to sequence melodies they hear, composers preserving musical ideas, or musicians learning performances note-by-note in their DAW.
Advanced Instrument Separation: Extract individual instruments with professional quality to enhance transcription accuracy or create custom practice tracks. Remove vocals for karaoke, isolate specific instruments for focused learning, or separate parts for detailed analysis.
These tools work together seamlessly — separate a piano part from a full mix for cleaner transcription, then convert it to both MIDI and sheet music for complete musical analysis and creative flexibility.
Music Education and Learning: Students and teachers use our transcription tools to convert recordings into readable notation and playable MIDI. Study complex jazz solos note-by-note in sheet music, or load difficult passages into your DAW as MIDI to slow down and practice. The combination of separation and transcription lets you isolate and learn any instrument part from any recording.
Composition and Arrangement: Composers capture musical ideas from recordings and convert them into editable formats. Transcribe that perfect chord progression to sheet music, or convert a melody idea into MIDI for further development. Our separation technology ensures you capture exactly the parts you want, not the entire mix.
Music Production and Remixing: Producers extract specific musical elements as MIDI for creative reuse. Convert a vocal melody to MIDI for harmonization, or transcribe a bass line for recreation with different sounds. The combination of separation and transcription provides unprecedented creative flexibility.
Performance Preparation: Musicians create custom practice materials by separating specific parts and converting them to notation. Remove your instrument to create practice backing tracks, or convert complex solos to sheet music for detailed study. Our specialized vocal remover is perfect for creating karaoke tracks.
Your music never leaves your device. This isn't just about privacy — it's about speed, reliability, and legal protection. Unlike LALAL.ai or Spleeter-based services, we process everything locally with no upload queues, no server downtime, and no concerns about unreleased material leaking. The AI model runs entirely in your browser using WebAssembly and WebGPU acceleration, delivering professional results without compromising your data security.
Local processing also means unlimited file sizes, instant processing start times, and no monthly usage limits beyond your chosen plan. We process a typical 4-minute song in under 30 seconds, and you can work with full albums, long DJ sets, or high-resolution audio without bandwidth concerns.
Despite the sophisticated AI technology underneath, Music Demixer is designed for simplicity. Drag and drop any audio file, choose your separation options, and get professional-quality stems in minutes. The interface scales from quick karaoke creation to detailed music production workflows.
Our quality settings let you balance processing time with separation precision. Free users get excellent basic quality, while Pro subscribers access the highest-fidelity models for professional music production and commercial applications.
We support all major audio formats: MP3, WAV, FLAC, AAC/M4A, OGG, AIFF, ALAC, WebM, WMA, OPUS, and more. Input any format and get professional outputs in either 24-bit WAV (maximum quality) or FLAC (50% smaller with lossless compression).
The system automatically handles sample rate conversion, bit depth optimization, and format compatibility, ensuring your separated stems integrate perfectly into any professional audio workflow or consumer application.
Free Plan: Get started with 3 transcription jobs per month using our core AI models. Perfect for students learning pieces, casual musicians, and anyone wanting to test the transcription quality before upgrading.
Pro Plan: Unlimited transcription with access to premium AI models, highest accuracy settings, and priority support. Essential for music educators, professional composers, and anyone who needs regular access to accurate music transcription and sheet music generation.
Both plans include the complete transcription suite — sheet music generation, MIDI conversion, and advanced instrument separation for enhanced accuracy. The difference is processing frequency, transcription precision, and access to premium AI models trained on larger musical datasets.
AI-powered music transcription represents a fundamental shift in how we learn, analyze, and work with recorded music. What was once locked away in final mixes can now be separated, transcribed, and converted into readable notation and editable MIDI. Music Demixer makes this breakthrough technology accessible to everyone, from music students to professional composers.
We're constantly improving our transcription accuracy, expanding instrument recognition capabilities, and refining our separation algorithms. The AI technology that powers Music Demixer is trusted by music educators, professional transcription services, and software developers worldwide. Over 4,000 musicians have used our platform in the past year alone.
Whether you're learning a complex piece, teaching music theory, documenting original compositions, or preparing performance materials, Music Demixer provides the AI-powered transcription tools you need. The combination of accurate separation and precise transcription, complete privacy protection, and intuitive design makes it the preferred choice for musicians who need to see what they're hearing.
