PURPOSE:To provide an audio device which automatically adds various effects, that are suitable to the taste of user, to acoustic signals such as musics and voices. CONSTITUTION:A storage section 31 outputs music data (L SIGNAL, R SIG NAL), effect switching position data (EF CHANGE) and music numbers (TUNE No.) to an output buffer 32 and outputs sampling clocks CKs to a signal processing section 30. The section 30 fetches the data EF CHANGE, the synchronization with clocks Cks. Employing the timing of the data EF CHANGE, the effects, specified by effect specifying data stored in an internal RAM set beforehand by a user, are added to the sound signals fetched through an A/D converter 34 and they are outputted to adders 35 and 36. The adders 35 and 36 mix them with the music data. D/A converters 37 and 38 digital-convert them and the signals are amplified by amplifiers 39 and 40 and are outputted from speakers 3a and 3b. |
