The passage around this formula
…shown to outperform prior codecs at comparable bitrates [ 7 ] . The mechanism gives a concrete, computable token rate. For a signal sampled at hertz, encoded with hop length h samples per frame, and quantized with residual stages of codebook size K each, the bitrate is . Every added quantizer stage buys reconstruction fidelity at a fixed, computable token-rate cost — the audio-codec analogue of the video tokenizer’s frame-versus-resolution trade, and just as unavoidable.
