A multimedia processing device and method for adjusting audio levels of program channels of multimedia content to reduce audio level disparities between multimedia content program channels. The method includes generating audio adjustment or offset information for at least one multimedia content program channel, and adjusting audio levels of the program channels based on the audio adjustment information. The audio adjustment information can be based on audio level samples taken from the multimedia content program channels or other suitable information. The audio adjustment information can be metadata transmitted as part of or separately from the multimedia content. The audio adjustment information also can be included within or associated with a channel map, as part of an additional channel map parameter, or in another method. The multimedia processing device, such as a set-top box, is configured to adjust the audio level of the received program channels of multimedia content.
