Abstract
A program asset is retrieved. The program asset has audio encoded at a first loudness setting and includes metadata specifying the first loudness setting. Dialog of the audio is identified. The loudness of the dialog is determined. The determined loudness is compared to the first loudness setting. The program asset is re-recorded at a second loudness setting corresponding to the determined loudness, if the first loudness setting and the determined loudness are different by more than a predetermined amount.
