In this paper we devise a methodology for analysing and subsequently manipulating a sound scene acquired by means of a uniform linear array of microphones. The array signal is transformed in the ray space, i.e. a domain where acoustic rays are points; here we extract the source position and orientation in space and its radiation pattern, while its signal is extracted by a near-field beamformer. These descriptors can be easily manipulated and provided to any parametric rendering system. Through simulations we have proven the capability of the proposed method to perform different manipulations.

Abstract

In this paper we devise a methodology for analysing and subsequently manipulating a sound scene acquired by means of a uniform linear array of microphones. The array signal is transformed in the ray space, i.e. a domain where acoustic rays are points; here we extract the source position and orientation in space and its radiation pattern, while its signal is extracted by a near-field beamformer. These descriptors can be easily manipulated and provided to any parametric rendering system. Through simulations we have proven the capability of the proposed method to perform different manipulations.
