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.
