Abstract:
1. A network audio processing circuit, comprising: a means for receiving a reproduced audio content signal; a microphone for providing a microphone output signal in accordance with ambient noise; a means for enabling the microphone output signal during first increments of time when the reproduced audio content signal is substantially off, and disabling the microphone output signal during second increments of time when the reproduced audio content signal is on; a signal processor, in communication with the means for receiving a reproduced audio content signal and the means for enabling and disabling the microphone output signal for: a means for enabling the network audio processing circuit to identify itself on the network; and at least one amplifier having an input coupled to an output signal of the signal processor and an output coupled to an input of a speaker, wherein the signal processor communicates with the at least one amplifier to determine whether or not a respective speaker is connected to the audio processing circuit and if a connected speaker is operational.
