PROBLEM TO BE SOLVED: To solve the problems, wherein sound is not synchronized, when combined and is not output correctly, even when reproduction speed is the same, in the case of performing reproduction at a high speed, while combining a plurality of audio signals of different audio frame sizes in the high-speed reproduction, in the high-speed reproduction characterized by the simplification of the decoding process. SOLUTION: The sound reproducing apparatus is provided with an audio composition means and a composition control means for controlling the video composition means. When the plurality of audio signals are combined and reproduced, the order of priority of the audio signals to be reproduced is determined, beforehand. The composition control means reproduces only the predetermined audio signals at a high speed, according to the priority order and is to set that the other audio signals which are not synchronized with the audio signal are not output. As a result, the high-speed reproduction that does not give a sense of incompatibility is realized, while decoding processing is simplified. COPYRIGHT: (C)2010,JPO&INPIT
