A New Multichannel Microphone Technique for Effective Perspective Control

Abstract

This paper introduces a new multichannel microphone technique that was designed to produce multiple listener perspectives. A listener perspective paradigm and the related spatial attributes are also proposed for the evaluation of spatial quality in acoustic recording and reproduction. The proposed microphone array employs five coincident microphone pairs, which can be transformed into virtual microphones with different polar patterns and directions depending on the mixing ratio. The results of interchannel correlation and informal subjective evaluations suggest that the proposed technique is able to offer an effective control over various spatial attributes
