PURPOSE: An information processing device, a method thereof, and a recording medium are provided to prevent the generation of noise by executing mute processing when erroneous decoding is decided. CONSTITUTION: Data inputted to an encrypting/decoding portion(21) are inputted to an erroneous decoding detector(23). The erroneous decoding detector decides if the data inputted are correctly decoded or not. If it is decided that the audio data inputted are not correctly decoded, the erroneous decoding detector does not output the audio data or outputs data indicating silence, thereby executing mute processing.
