发明名称 METHOD AND DEVICE FOR RESTORING A MULTICHANNEL AUDIO SIGNAL IN A LISTENING ZONE
摘要 The method comprises: — a multichannel audio signal analysis step (E20) comprising extraction of a multichannel component (Cl), referred to as an omnidirectional component, verifying a predetermined similarity criterion between at least two of the channels thereof; and — a restoration step (E30,E40,E50) in the listening zone, using all or some of N loudspeakers included in the listening zone, of the omnidirectional component and of a residual multichannel component (C2) of the multichannel audio signal obtained after extraction of the omnidirectional multichannel component, the omnidirectional multichannel component (Cl) being restored in a manner providing uniform intensity throughout the listening zone, and the residual multichannel component (C2) being restored by using a sound spatialization technique, creating a number K of virtual sound sources restored in the listening zone.
