Reconstruction of the Virtual Microphone Signal Based on the Distributed Ray Space Transform

摘要

In this paper we propose a technique for the reconstruction of the sound field at arbitrary positions based on a parametric sound field description. The methodology consists in the estimation of the sources model parameters (source position, radiation pattern and source signal), starting from the signals acquired by arbitrarily distributed microphone arrays. Given the model parameters it is possible to synthesize the signal of a virtual microphone at an arbitrary position and with an arbitrary pickup pattern.
