Abstract:
A multi-channel sound transmission method comprising the steps of:obtaining a plurality of spatial pulse responses using at least three excitation locations and at least three closely proximate microphone locations, each microphone location having at least one variably-oriented directional microphone for receiving the spatial pulse responses; convolving a plurality of directly received sound signals, conforming at least in number to the plurality of spatial pulse responses; locally distributing the convolved signals through reproduction loudspeakers; and swivelling the at least one directional microphone around a center point so as to receive data from a plurality of receiving directions; wherein there are at least two reproduction loudspeakers, each loudspeaker corresponding to one of the plurality of receiving directions and being oriented in a direction opposite to the corresponding receiving direction.
