Demucs v4 / HTDemucs-ft (MLX)
Music source separation into drums, bass, other and vocals. Converted to MLX from the maintained Demucs v4 source and the official HTDemucs-ft weights.
Files
Four checkpoints, one per stem, 84 MB each:
| file | official upstream checkpoint |
|---|---|
drums.safetensors | f7e0c4bc |
bass.safetensors | d12395a8 |
other.safetensors | 92cfc3b6 |
vocals.safetensors | 04573f0d |
Each .json beside a checkpoint is that stem's architecture configuration.
HTDemucs-ft ships a separately fine-tuned checkpoint per stem, and each one emits all four sources — the stem it is named for is the one it was tuned to produce best. Extracting a single stem therefore means downloading one 84 MB file, and a full four-stem separation runs the network four times.
fp32 only; no quantized conversion is published.
