Dual-Branch Codec With Orthogonality Constraint and Knowledge Distillation for Noisy Environment

Audio codecs, by discretizing continuous audio signals into finite token sets, achieve high-quality reconstruction at low bitrates in clean environments. However, real-world speech often deviates from ideal conditions, particularly in noisy environments with low signal-to-noise ratios (SNRs), limiti...
