What it does
Audio nodes for ComfyUI: Hybrid Demucs separation into bass, drums, other and vocals, plus combining, cropping, tempo detection, tempo matching, speed shifting and pulling audio out of video. Only useful if you already run ComfyUI. Separation quality depends on the mix and instruments bleed between stems. Stems pulled from commercial music are for your own use, not for distribution. MIT.
