About Spleeter

Spleeter is a powerful open-source source separation library developed by Deezer that utilizes deep learning to isolate individual musical components from audio files. It allows users to split tracks into two, four, or five distinct stems, including vocals, drums, bass, and piano. Designed primarily for developers and audio engineers, its key differentiator is its exceptional processing speed and high-quality output, making it a foundational backend technology for numerous third-party music production applications and automated audio analysis workflows across the global media industry.
