Cisco DX80 includes an Acoustic Echo Canceller (AEC) and laptop shadowing. Users at the far end of a call experience clear audio quality even if the user puts an obstacle, such as a laptop, in front of one of the microphones. If the current microphone is blocked by an object, the device automatically switches to the other microphone array in the other foot.
Cisco DX80 also includes two microphone array beam forming. If the user moves out of the beam (that is, out of the camera view), the sound sent to the far end weakens. All sound sources that are not located within the pickup beam (in front of the unit) attenuate.
