Abstract
A continuous stage variable is generated with a state machine of a controller. A level of transmit attenuation and a level of receive attenuation are generated by the controller using the continuous state variable. Local audio signals generated with a local microphone are attenuated with a transmit attenuator at the level of transmit attenuation for transmission to a remote node. Remote audio signals received from the remote node are attenuated with a receive attenuator at the level of receive attenuation for playback at a local speaker.
