Best VPS for Demucs (Self-Hosted)

Demucs is Meta's state-of-the-art open-source music source separation tool. With over 10,000 GitHub stars, it uses a hybrid spectrogram and waveform model to split any mixed audio track into individual stems: vocals, drums, bass, and other instruments. Demucs v4 (Hybrid Transformer) achieves the best separation quality available in open-source, rivaling commercial solutions. It supports batch processing of multiple files, real-time separation on GPU, and can handle both music and general audio. The tool includes a simple Python API and CLI, processes audio in seconds on GPU, and works on CPU for slower but functional operation. Demucs is widely used by musicians, DJs, and content creators for creating karaoke tracks, isolating vocals, and remixing.
