Locating Image Sources from Multiple Spatial Room Impulse Responses

Measured spatial room impulse responses have been used to compare acoustic spaces. One way analyze and render such is apply parametric methods, yet those methods bound single measurement locations. This paper introduces a method that locates image sources from measured at multiple source receiver positions. The aligns the measurements common coordinate frame groups stable direction-of-arrival estimates find performance of validated with three case studies—one small two concert halls. studies show able locate most prominent even in complex spaces, providing new insights into available Spatial Room Impulse Response (SRIR) data starting point for six degrees freedom (6DoF) rendering.
