Based on XMOS’s chipset, the XVF3000, the upgraded mic array offers several improvements. The quality of the onboard algorithms has been improved, specifically for the AEC (Acoustic Echo Cancellation) algorithm. It has been upgraded into a full-duplex solution, which means that the device can continue to play audio while also recording its environment. It also features barge-in support for new voice/sounds when they enter the environment, providing them a chance to be heard. The chipset also allows the ability to customize microphone spacing and can be configured as a circular or linear array.
