New "Equalizer" method enhances neural audio codecs by separating signal gain and shape

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced a new methodology called "The Equalizer" for neural audio codecs (NACs) that separates the signal's energy (gain) from its structure (shape). This decomposition aims to improve robustness against variations in input signal levels, which currently cause inefficiencies and suboptimal performance in existing NACs. By processing the shape vector with the NAC and transmitting the gain separately, this approach promises significant gains in bitrate-distortion performance and a reduction in quantizer complexity, as demonstrated in experiments with four prominent speech codecs.

    The Equalizer: Introducing Shape-Gain Decomposition in Neural Audio Codecs

    arXiv:2602.15491v2 Announce Type: replace-cross Abstract: Neural audio codecs (NACs) typically encode the short-term energy (gain) and normalized structure (shape) of speech/audio signals jointly within the same latent space. As a result, they are poorly robust to a global variat…
