 ## Tokenizer checkpoint
 
-`rvq_teacher/epoch_22.pt` is the final R16 tokenizer, trained on LibriSpeech
-plus the full Emilia set with a learnable codebook at a 10x codebook learning
-rate (`streamalign_r16`).
-It replaces the earlier LibriSpeech-only `epoch_16.pt`.
+The checkpoint under `rvq_teacher/` is the final R16 tokenizer, trained on

 Load it with `RVQ_R=16` and `RVQ_CODEBOOK_SIZE=512`, and leave
 `RVQ_CODEBOOK_DIM` unset: `codebook_dim` defaults to `feat_dim=256`, which is
