Stereophonic sound reproducing system and stereophonic sound reproducing apparatus

摘要

A stereophonic sound reproducing system including: a stereophonic sound reproducing device which provides a sound field space giving realistic sensations to a listener by publicly addressing sounds from speakers corresponding to inputted plural sound signals on the basis of the inputted plural sound signals; a main speaker which is arranged in a forward direction of the listener and publicly addresses the sound signal at a position which makes the listener include in an angle of sound spread; and a surround speaker which is arranged in a forward direction of the listener and publicly addresses the sound signal toward wall surfaces of the sound field space, wherein the stereophonic sound reproducing system includes: a signal adjustment device which adjusts the surround signal by adjusting frequency characteristics of a surround sound signal which represents the sound signal which inputted so as to be publicly addressed from the surround speaker on the basis of a propagation circumstance at the time of public address; a delay time addition device which adds a delay time corresponding to the surround sound signal which is publicly addressed from the surround speaker to a main signal representing the inputted sound signal which is publicly addressed from the main speaker; and an output device which outputs the main signal with the delay time added to the main speaker and outputs the surround sound signal with the frequency characteristics adjusted to the surround sound speaker.
