Sound system, sound output apparatus and the sound signal supply device

PROBLEM TO BE SOLVED: To more appropriately correct acoustic characteristics according to the type of a speaker. SOLUTION: When a sound signal for emitting sound is received (S3; YES), a speaker device of a conference terminal superimposes attribute information to the sound signal at predetermined timing (S5), and emits the sound (S6). The conference terminal collects the emitted sound by a microphone (S7), and extracts the attribute information from the sound signal representing the sound (S8). The conference terminal specifies a correction amount associated with the extracted attribute information (S10) in an acoustic characteristic correction table in which each piece of attribute information is associated with the correction amount. Then, the conference terminal supplies the sound signal to the speaker device after correcting sound data to be supplied to the speaker device by the specified correction amount (S11). The speaker device emits the sound according to the sound signal after correction (S12). COPYRIGHT: (C)2010,JPO&INPIT
