The python version of scripts now perfermance badly(may have some logical errors), please refer to apply_cgmm_beamforming.m, which works ok.
Update: Newest version in cgmm-mask-estimator
install voicebox for MATLAB first.
copy run_cgmm_beamforming.sh and apply_cgmm_beamforming.m to local/, then run followings instead of baseline local/run_beamform_6ch_track.sh commands
local/run_cgmm_beamforming.sh --nj 15 $chime4_data/data/audio/16kHz/isolated_6ch_track/ $enhancement_data- 6ch
