Abstract:
1. An audio mixing/reproducing device comprising: an audio decoding unit configured to decode an encoded audio input signal to generate a first audio signal; an audio mixing unit configured to mix the first audio signal with a non-encoded second audio signal to generate a third audio signal; an audio encoding unit configured to encode the third audio signal to generate an encoded audio output signal; and a switching unit configured to switch between operations of each of the audio decoding unit and the audio encoding unit, wherein the audio decoding unit and the audio encoding unit each support two or more encoding schemes, and the switching unit, when switching the encoding scheme of the audio decoding unit from a first encoding scheme to a second encoding scheme, controls the audio decoding unit and the audio encoding unit so that the encoding scheme of the audio encoding unit is switched from the first encoding scheme to the second encoding scheme in synchronization with the switching of the encoding schemes in the audio decoding unit.
