Stem Separator
Enhance your audio workflow and unlock creativity with stem separation.
Our AI-powered technology, developed by IRCAM-Centre Pompidou, delivers high-quality isolation of vocals and the main stems. By combining cutting-edge AI with advanced signal processing, we ensure clean, reliable stem extractions for professional audio applications.

Stem separation expertise
Beyond isolation: True demixing
Our separator doesn’t just isolate stems, it demixes them, delivering pristine separation with no quality loss. The output stems perfectly reconstruct the original track, even if they weren’t recorded separately!
Stem separation: new horizons
Process longer audio files
Handle tracks up to 1 hour and 30 minutes, with unmatched accuracy and integration capabilities, ideal for separation of full-length tracks and live recordings.
Advanced stem separation
For production music libraries, record labels & publishers, music producers, sync platforms, music learning and karaoke solutions.
4-stem extraction
Separate vocals, drums, bass, and other instruments with industry-leading accuracy and artifact-free results, guaranteed.
Industry-grade SDR
With a 9.3 dB Signal-to-Distortion Ratio (SDR), our separator outperforms models like Demucs (Meta), Sony, and Deezer’s Spleeter.
API-First
Enables seamless integration into existing workflows, perfect for large-scale stem separation tasks.
Stem separation isn’t just a tool, it’s a revenue driver
