AB  - Multichannel acoustic signal processing is predicated on the fact that the inter channel relationships between the received signals can be  exploited  to  infer  information  about  the  acoustic  scene.   Recently there has been increasing interest in algorithms which are applicable in dynamic scenes, where the source(s) and/or microphone array  may  be  moving.   Simulating  such  scenes  has  particular  challenges  which  are  exacerbated  when  real-time,  listener-in-the-loop evaluation of algorithms is required. This paper considers candidate pipelines for simulating the array response to a set of point/image sources  in  terms  of  their  accuracy,  scalability  and  continuity.   Anew approach,  in which the filter kernels are obtained using principal component analysis from time-aligned impulse responses,  is proposed.  When the number of filter kernels is≤40the new approach achieves more accurate simulation than competing methods.
