PROBLEM TO BE SOLVED: To synchronize plural contents which are not temporally synchronized in advance, without a time lag.SOLUTION: A feature amount calculation unit calculates the sound feature amount of a sound included in a content including sounds, and a synchronization-related information generation unit generates, on the basis of the sound feature amount, synchronization information for synchronization of plural contents containing identical or similar sound signal components. A synchronization unit generates a synthetic content obtained by synchronizing and synthesizing the contents, using the synchronization information. This technique can effectively be applied to a case of synchronizing plural contents of a musical performance, singing, and dancing using an identical music, for example. |
