A Demo of the PercepNet Low-Complexity Real-Time Speech Enhancement Algorithm

This demo introduces the PercepNet algorithm, which combines signal processing, knowledge of human perception, and deep learning to enhance speech in real time. PercepNet ranked second in the real-time track of the Interspeech 2020 Deep Noise Suppression challenge, despite using only 5% of a CPU core. We've previously talked about PercepNet here, but this time we go into the technical details of how and why it works.
