Abstract

Lateralization in stereo-rendered acoustic fields with controlled interchannel cross-correlation properties was explored in subjective listening tests. Participants indicated the perceived lateral locations of a series of 2 ms stereo white noise bursts with specified interchannel cross-correlation properties. Additionally, participants were asked to indicate the spatial location and apparent source width of a series of 2 sec white noise bursts composed of one-thousand 2 ms bursts with specified interchannel cross-correlation. The distribution of peak locations in the signals’ cross-correlation corresponds to the perceived spatial extent of the auditory image. This illustrates the role of the averaging time in the short-time windowed cross-correlation model of binaural hearing and how the coherence properties of audio signals determine source image properties in spatial audio rendering.
