Audio commentary

Audio commentaries are audio tracks provided on DVD and Blu-ray Disc releases, separate from the regular soundtrack. Often a director, writer, or actor will discuss details about the production, story, and so forth on a commentary. A single disc can hold several commentaries (as many audio tracks as space allows), and they can be generally selected from a menu of the disc. Often the discussion by the participants will be on top of the dialog and regular soundtrack, both of which have their volumes lowered for better comprehension of the commentary dialog.
