Abstract
A plural-channel audio signal (e.g., a stereo audio) is processed to modify a gain (e.g., a volume level or loudness) of an estimated dialogue signal (e.g., dialogue spoken by actors in a movie) relative to other signals (e.g., reflected or reverberated sound). In some aspects, a controller is used to control master volume and dialogue volume. In some aspects, one or more graphical objects and/or user interface elements are used to indicate volume levels and other information.
Claims21
An apparatus comprising:
- a dialogue volume control;
- a master volume control;
- and
- a circuit operatively coupled to the dialogue volume control and the master volume control and configurable for generating a dialogue volume control signal and a master volume control signal for use in separately adjusting the dialogue volume and the master volume of an audio signal, respectively.
1 more element
An apparatus comprising:
- a volume control;
- a dialogue volume control select;
- and
- a circuit operatively coupled to the volume control and configurable for generating a dialogue volume control signal if the dialogue volume control select is activated, and for generating a master volume control signal to the device if the dialogue volume control select is not activated.
1 more element
A method comprising:
- receiving a first volume control signal;
- receiving a second volume control signal;
- responsive to the first volume control signal, displaying a first graphical object for indicating a first volume level;
- and
- responsive to the second volume control signal, displaying a second graphical object within or proximate to the first graphical object for indicating a second volume level relative to the first volume level.
2 more elements
A method comprising:
- obtaining a plural-channel audio signal;
- estimating a center channel signal and at least left and right channel signals using the audio signal;
- modifying a first gain of the center channel signal using a gain factor generated by a dialogue volume control;
- generating a combined channel signal including the left and right channel signals and the modified center channel signal;
- and
- modifying a second gain of the combined channel signal using a master volume control.
3 more elements
A system comprising:
- a controller configurable for generating a dialogue volume control signal;
- and
- a receiver configurable for receiving the dialogue volume control signal, and for using the dialogue volume control signal to modify a dialogue volume level of a plural-channel audio signal being processed by the television receiver without modifying the volume level of at least a portion of the plural-channel audio signal.
