Spleeter

About

Deezer's fast pretrained source separation library (ISMIR 2019). U-Net on magnitude spectrograms, TensorFlow-based. Separates into 2/4/5 stems. GitHub: deezer/spleeter (28.2k stars). Install: pip install spleeter. Very fast but lower quality than Demucs on acoustic music.

Relevance

Quick-and-dirty separation for bluegrass. Speed advantage may be useful for batch processing, but quality gap vs. Demucs is significant on acoustic recordings. Same "other" stem limitation.

Mentions

• ../entities/demucs — higher quality alternative
• ../entities/open-unmix — more hackable alternative
