Abstract
The stereo decoding unitperforms steps S-and S-below (step S). The stereo decoding unitobtains a signal concatenating a sum signal (a signal configured by addition of sample values of corresponding samples) of the monaural decoded sound signal for the section Y and the additional decoded signal for the section Y and the additional decoded signal for the section X, as a decoded downmix signal for the section Y+X (step S-) instead of step S-performed by the stereo decoding unitof the first embodiment and obtains and outputs the decoded sound signals of the two channels from the decoded downmix signal obtained at step S-by the upmix processing using the characteristic parameter obtained from the stereo code CS, using the decoded downmix signal obtained at step S-instead of the decoded downmix signal obtained at step S-(step S-).
