The encoding device stores information that indicates the presence or absence of extended information in a bitstream. During decoding of the encoded bitstream, extended information is retrieved depending on the retrieved information indicating the presence or absence of extended information, and on the basis of said retrieved extended information, processing is implemented on audio data. |
