# ASTRAL-quantization (mirror)

An unmodified, file-for-file mirror of
[Plachta/ASTRAL-quantization](https://huggingface.co/Plachta/ASTRAL-quantization),
taken 2026-08-26. All credit to Plachta; GPL-3.0 as licensed upstream
(full text in LICENSE).

From the original card: "This is a speech linguistic content quantizer
[that] operates on Hubert-large features. It is trained with explicit ASR
supervision to preserve more linguistic content while discarding more
speaker traits."

Contents: the bsq32 and bsq2048 quantizers (full `pytorch_model.bin` +
`*_light.pth` + configs). The light checkpoints are the content
extractors of Seed-VC V2.

Mirrored for use in a local macOS music app — archival insurance against
the original (a personal account) going away; the app downloads from the
original while it exists.
