Abstract
The process control unit (11) of a microcomputer (1) controls a decoder (21) to decode an input signal, and acquires the voice format information of an input signal. The process control unit (11) calls the processing method of matrix processing stored in a storage unit (12) based on the acquired voice format information. The process control unit (11) further acquires encode channel-related information from an input signal. When the encode channel is 2-channel, the process control unit (11) controls a surround processor (22) to perform matrix processing on an input signal and output a multi-channel-based voice. An acoustic device capable of setting a reproduction mode according to an input signal is realized.
