Investigations on an Early-Reflection-Free Model for BRIRs

Simulating the late reverberation of a room using a synthetically generated reverberation tail is a common practice in the design of artificial reverberators. Binaural reverberators could benefit from better knowledge of the perceptual cues that are relevant for the reverberation tail. In this study the use of filtered white Gaussian noise instead of the original tail was subjectively evaluated. Matching the interaural coherence in each frequency band produced better results than full-band matching. In some cases time-dependent matching improved quality. Results are based on subjective studies.
