We have recently talked about making soundscapes from photographs and a group of professional recording artists joining forces to document the exquisite sounds of nature. The real world, no doubt, is much more sonically diverse and full. Is there a way to capture the characteristic sounds of the world we live in? Is there then a way for me to travel sonically to hear what you hear in another part of the world?
A precedence effect model is described that can use a binaural signal to robustly localize a sound source in the presence of multiple reflections for the frontal horizontal plane. The model also estimates a room impulse response from a running binaural signal and determines the spatial locations and delays of early reflections, without any prior or additional knowledge of the source. A dual-layer cross-correlation/auto-correlation algorithm is used to determine the interaural time difference of the direct sound source component and to estimate a binaural activity pattern.
