Conference Paper

Analysis of Spatial Room Impulse Responses Assuming Superposition of Plane Waves

Authors: Tervo, Sakari; Pätynen, Jukka

AES Conference: 55th International Conference: Spatial Audio · Paper P-15 · August 2014

Abstract

This paper studies the analysis of spatial room impulse responses recorded with a microphone array, at a single frequency, and assuming more than one plane wave per analysis window. A parametric method, weighted subspace fitting, developed in array processing some 20 years ago, is applied to the analysis of the spatial room impulse responses. The previous approaches for spatial room impulse response analysis are known to have limitations since they assume only plane wave per time window. This paper shows by room acoustic simulations that assuming more than one plane wave improves the analysis, which will benefit the synthesis of spatial room impulse responses in sound reproduction techniques.
