HTDemucs Models (Safetensors)

4/6-Stem Source Separation — Vocals, Drums, Bass, Other (+Guitar, Piano)

Original Source by Facebook Research · MIT License

Each model has a matching *_config.json with architecture parameters (sources, sample rate, channels).

What HTDemucs Does

HTDemucs (Hybrid Transformer Demucs) separates mixed audio into individual stems:

  • Vocals — Singing, spoken word
  • Drums — Percussion, kick, snare, hi-hat
  • Bass — Bass guitar, synth bass
  • Other — Everything else (keys, synths, FX)
  • Guitar — (6-stem model only)
  • Piano — (6-stem model only)

Key Features

  • Real-time capable on GPU
  • Adjustable segment size for VRAM control
  • Best-in-class separation quality (htdemucs_ft)
  • ~4–6 GB VRAM
