Abstract
Systems and methods for improving the audio quality in a living-room type of environment having multimedia equipment are described. The audio signals emanating from various speakers may be modified/altered, so as to capture audio signals with the highest signal-to-noise ratio. In the context of a video/audio call, where the positions of the microphone and speakers are generally fixed, the speaker outputs may be controlled/modified to provide an improved signal-to-noise ratio. The audio emanating from the central speaker may be subdued or eliminated to reduce significantly the problems that occur due to the audio from the center speaker being captured by the microphone, which is typically in close proximity to the center speaker. The audio may be provided to the speakers by various ways, such as HDMI, RCA, and so on.
