The "Clean effects" flag (0x01) should indicate that the audio track is a
special one, containing no language (no speech) but just the effects (background
sounds like steps, shutting doors, noise of car/train etc). 

Some broadcasters incorrectly attach this flag to normal audio tracks which are
supposed to use the default value 0x00.

       With kind regards,
