Echo control based on state of a device
摘要:
A device and a corresponding method are provided to tune parameters of an echo control process without re-initializing the echo control process and without interrupting a playback process. A state of the device and environment around the device is computed during use of the device given information from sensors. Such sensors can give information on the position of the device, the orientation of the device, the presence of a proximate object, or handling of the device resulting in occlusion of microphones and loudspeakers, among other things. The computed state of the device is mapped to an associated device state code from among a plurality of device state codes. The parameters of the echo control process are tuned either according to the associated device state code, or a change in such a code, during use of the device.
