Switchcodec: Adaptive residual-expert sparse quantization for high-fidelity neural audio coding

概要

arXiv:2601.20362v2 Announce Type: replace-cross Abstract: Recent neural audio compression models often rely on residual vector quantization for high-fidelity coding, but using a fixed number of per-frame codebooks is suboptimal for the wide variability of audio content-especially for signals that a…
