Segmentation and Analysis of Early Reflections from a Binaural Room Impulse Response

In this paper, a novel method for analysis of binaural room impulse responses is presented. Individual reflections are localized in time and frequency from a measured binaural room impulse response based on the continuous cross-wavelet transform (XWT). The directions of the reflections are then analyzed based on KEMAR and CIPIC reference data lookup, and compared a previous approach. Analysis of the directions and arrival times of reflections allows detailed study of measured binaural room impulse responses. The reflections can also be resynthesized based on the continuous wavelet transform (CWT) and spread apart in time, resulting in a slow-motion room impulse response that can be useful for room acoustics design as well as in teaching room acoustics.
