MuQ: Music SSL via Mel Residual Vector Quantization

Trains a self-supervised music representation model to predict tokens from Mel Residual Vector Quantization (Mel-RVQ), a residual linear-projection quantizer of the Mel spectrum that stabilizes SSL target extraction, beating prior music SSL with only 0.9K hours of data (scaling to 160K with iterative training) and yielding MuQ-MuLan, a contrastive music-text model with SOTA zero-shot music tagging.
