Abstract
Methods and systems are disclosed for echo suppression of an input audio signal. A multimedia system and a remote control unit are configured to adaptively and dynamically preform calibration processes for obtaining sets of echo suppression parameters. The sets of echo suppression parameters are used to generate an audio signal from an input audio. When rendered by a speaker, the generated audio signal produces echo-suppressed sound of the input audio signal at one of more locations.
