Document Type and Number:
WIPO Patent Application WO/2006/004099
Kind Code:
A1
Abstract:
A sound reproducing system that can appropriately analyze the reverberation characteristics of a reinforced sound including the direction from which the reverberation components are coming, and that provides more natural sounds and enhanced presence. A surround system (100) comprising a speaker system (130); a signal processing apparatus (120) that recognizes the reverberation characteristic of a listening room (10) to adjust, based on the recognized reverberation characteristics, the reverberation components of a reinforced sound source; and a microphone array (140) comprising a plurality of microphones (M) arranged in the listening room (10) and having the same characteristics with the array pitch between the microphones (M) decided in advance; wherein when the sound source is reinforced from the speaker system (130) into the listening room (10), the microphone array (140) collects, at a particular listening position in the listening room (10), the reinforced sound.
