Binaural Reproduction of 22.2 Multichannel Sound with Loudspeaker Array Frame

Authors: Matsui, Kentaro; Ando, Akio

AES Convention 135 · Paper 8954 · October 2013

Abstract

NHK has proposed a 22.2 multichannel sound system to be an audio format for future TV broadcasting. The system consists of 22 loudspeakers and 2 low frequency effect loudspeakers for reproducing three-dimensional spatial sound. To allow 22.2 multichannel sound to be reproduced in homes, various reproduction methods that use fewer loudspeakers have been investigated. This paper describes binaural reproduction of 22.2 multichannel sound with a loudspeaker array frame integrated into a flat panel display. The processing for binaural reproduction is done in the frequency domain. Methods of designing inverse filters for binaural processing with expanded multiple control points are proposed to enlarge the listening area outside the sweet spot.
