BEATs-tokenizer-AS2M-iter1

BEATs base tokenizer (VQ-KD) — AudioSet-2M, iteration 1

Acoustic VQ tokenizer (1024-entry codebook) trained on AudioSet-2M with ESPnet, following BEATs (Table 4). Distilled with the iteration-0 BEATs encoder as teacher; used to generate the discrete targets for iteration-1 encoder pre-training. Produced by the egs2/audioset/ssl1 recipe (external_tokenizer_model).
