Patent ID: 8184834

Claim:
An apparatus for processing a multi-channel audio signal, comprising: a dialogue estimator configurable for receiving the multi-channel audio signal including at least a dialogue signal, for determining a gain value for at least one channel of the multi-channel audio signal, for determining an inter-channel correlation between at least two channels, determining a location of the dialogue signal based on at least one of the gain value and the inter-channel correlation, and for identifying the dialogue signal based on the location of the dialogue signal; a dialogue volume control; a master volume control; and a circuit operatively coupled to the dialogue volume control, the master volume control and the dialog estimator, configurable for receiving at least one of a dialogue control signal and a master control signal, the dialogue control signal being used for adjusting the dialogue volume of the identified dialogue signal and the master control signal being used for adjusting the master volume of the multi-channel audio signal, respectively, and modifying at least one of the dialogue volume and the master volume based on at least one of the dialogue volume control signal and the master volume control signal.
