What is Free Music Demixer?

Free Music Demixer is an AI tool that separates audio tracks into individual stems, such as vocals, drums, bass, and instruments. You upload a song, and the software analyse it to extract these components as separate audio files. The tool runs entirely in your browser or on Android; your files stay on your device and are never sent to external servers, which means your music remains private. It's useful for musicians, producers, DJs, and anyone who needs to isolate specific parts of a song. The free version offers unlimited processing with standard quality, while a paid tier provides higher-quality separation models for more demanding audio work.
