Mel-McNet reduces reported computation for multichannel speech enhancement by compressing microphone features into a perceptually motivated Mel-frequency representation while retaining spatial cues. On six-channel simulated CHiME-3, it uses 46.96 versus McNet’s 115.13 FLOPs per second, with both at 4.4% WER and DNSMOS scores of 3.14 versus 3.12. However, WB-PESQ and STOI are lower; results are limited to this benchmark.
