APPARATUS AND METHOD FOR CONTROLLABLE ACOUSTIC ECHO CANCELLATION

This abstract first appeared for US patent application 20250006213 titled 'APPARATUS AND METHOD FOR CONTROLLABLE ACOUSTIC ECHO CANCELLATION

Original Abstract Submitted

a method for a communications system between at least three devices, the method comprising: determining at least one device of the at least three devices is an ambient transmitting device, the ambient transmitting device configured with a controllable acoustic echo canceller to reduce echoes, wherein the at least one ambient transmitting device is configured to generate at least one ambient audio signal, and wherein the remaining at least two devices are non-ambient devices; controlling the at least one ambient transmitting device to reduce the effect of the controllable acoustic echo canceller; and applying at least one delay difference to at least one communications path between non-ambient devices.
