BandTok tokenizes Mel-spectrograms as independent time-frequency band tokens from a single codebook and pairs it with 2D RoPE in an autoregressive model to improve music generation over residual multi-codebook tokenizers.

ECC integrates hyperprior side information, channel-wise context, latent residual prediction, temporal modeling, and entropy skip into a learned entropy model, yielding 39.9% and 76.3% average BD-rate reductions on ViSQOL and PESQ over baselines.
FMelCodec is a three-stage mel-spectrogram codec using 640x VQ compression, conditional flow matching refinement, and HiFi-GAN reconstruction that reports higher quality than prior methods at 250 bps for 16 kHz speech.
