Neural Audio Codecs' Low Frame Rate Degradation Linked to Training Configuration
A new study by Gichamba and Busogi investigates the mechanisms behind low frame rate degradation in neural audio codecs. The researchers found that a quality cliff at 6.25 Hz is caused by suboptimal training configuration, not by phonemic collisions or codebook saturation. After correcting the training setup, the codecs perform smoothly down to 3.1 Hz and 1.6 Hz, suggesting that low frame rate efficiency gains are more accessible than previously assumed.
