Abstract: The present invention relates to a method of selecting sound contents transmitted by transmission channels and received by an audio or audiovisual receiver. A user first selects a received content and starts playback. Then, the receiver automatically searches among the contents transmitted by the transmission channels for a content whose audio parameters have values close to the values of a previously selected content and plays it back at the end of the current content.

According to a refinement, the receiver has a memory that makes it possible to offset the playback of the content in time and thus best synchronize the playback of the various selected contents. The invention also relates to an appliance capable of selecting audio contents originating from several channels and having similar audio characteristics, and playing them back automatically.
