Abstract
The present invention provides a sound reproducing system capable of accurately analyzing a reverberation characteristic of amplified sound including an arrival direction of a reverberation component, which is more natural, and has higher realistic sensation. A surround system 100 has a speaker system 130, a signal processing apparatus 120 for recognizing a reverberation characteristic of a listening room 10 and adjusting a reverberation component of sound source to be amplified on the basis of the recognized reverberation characteristic, and a microphone array 140 constructed by a plurality of microphones M disposed in the listening room 10 and having the same characteristics, and in which distances among the microphones M are determined in advance. In the case where sound source is amplified and output from the speaker system 130 to the listening room 10, the microphone array 140 collects amplified sound in a specific listening position in the listening room 10.
