1. An apparatus for processing audio signals, comprising:
- (a) a transmit attenuator for attenuating local audio signals generated by a local microphone for transmission to a remote node;
(b) a receive attenuator for attenuating remote audio signals received from the remote node for playback at a local speaker; and
(c) a controller, electrically connected to the transmit attenuator and the receive attenuator, for controlling a level of transmit attenuation for the transmit attenuator and a level of receive attenuation for the receive attenuator, wherein;
the controller receives, from the remote node, remote audio information corresponding to the remote audio signals;
the remote audio information is distinct from the remote audio signals;
the remote audio information has been generated by the remote node based on the remote audio signals; and
the controller uses the remote audio information to generate the level of transmit attenuation and the level of receive attenuation without having to implement local processing of the remote audio signals to generate a locally-generated version of the remote audio information.

Abstract
Remote audio information corresponding to remote audio signals are received by a controller from a remote node. A level of transmit attenuation and a level of receive attenuation are generated by the controller using the remote audio information. The local audio signals 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.

10. A computer-implemented process for processing audio signals, comprising the steps of:
-
(a) receiving, by a controller from a remote node, remote audio information corresponding to remote audio signals, where; the remote audio information is distinct from the remote audio signals; and the remote audio information has been generated by the remote node based on the remote audio signals; (b) generating, by the controller, a level of transmit attenuation and a level of receive attenuation using the remote audio information without having to implement local processing of the remote audio signals to generate a locally-generated version of the remote audio information; (c) attenuating, with a transmit attenuator at the level of transmit attenuation, the local audio signals for transmission to a remote node; and (d) attenuating, with a receive attenuator at the level of receive attenuation, remote audio signals received from the remote node for playback at a local speaker. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
