Ideal binary masking isolates time-frequency tiles where target dominates masker

Evidence

To generate the glimpsed stimuli, an ideal binary mask was applied separately to the two ears of the binaural stimuli using the methods of Wang ( 2005 ) and Brungart et al. ( 2006 ). In short, the signals were analyzed using 128 frequency channels between 80 and 8000 Hz, and 20-ms time windows with 50 % overlap. Tiles with target energy exceeding masker energy were assigned a mask value of one and the remaining tiles were assigned a value of zero. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1753
