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.
Claims32
A method of correcting an audio level of a program asset, comprising:
- retrieving the program asset, the program asset having audio encoded at a first loudness setting and comprising metadata specifying the first loudness setting;
- identifying dialog of the audio;
- determining a loudness of the dialog;
- comparing the determined loudness to the first loudness setting;
- and
- re-encoding the program asset 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.
A system for correcting an audio level of a program asset, the system comprising:
- a memory operative to store the program asset, the program asset having audio encoded at a first loudness setting and comprising metadata specifying the first loudness setting;
- and
- a processor coupled to the memory, the processor programmed to:
- retrieve the program asset;
- identify dialog of the program asset;
- determine a loudness of the dialog;
- and
- re-encode the program asset 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.
