AI MusicFree

Spleeter is Deezer's open-source music source separation library that uses deep learning to separate audio tracks into stems (vocals, bass, drums, other) at high speed. It was one of the first widely-adopted open-source stem separators and remains popular for batch processing workflows due to its speed and ease of deployment. Developers, audio engineers, and researchers use Spleeter to build stem separation pipelines, process large music archives, and create karaoke and acapella versions of songs programmatically.
