Direction-Based Speech Enhancement Using Multichannel Subband-Fullband Neural Network

Here are some demos on the proposed direction-based multichannel subband-fullband method. Find the paper here: (

Audio and video is taken from the Easycom dataset by Donley et al. (

Note that the Maximum-Directivity MVDR baseline method shown here is suboptimal for multi-speaker enhancement, which has therefore been disabled for this method.
