Abstract:
1. A set of headphones for producing an acoustic signal characterized by first and second channel audio signals, the set of headphones comprising: a number of speakers; an interface configured to receive an analog input signal including the acoustic signal and configuration programming data generated such that the configuration programming data is combined with the first channel audio signal, the interface including: an audio processing circuit coupled to receive the first channel and second channel audio signals and configured to output the acoustic signal to the speakers, wherein the audio processing circuit is responsive to a programming signal to program programmable audio processing functionality that characterizes a configuration of the audio processing circuit for processing the acoustic signal; an extraction circuit having an input to receive the first channel audio signal combined with the configuration programming data and configured to extract the configuration programming data; a configuration circuit having an input to receive the configuration programming data and having an output to provide the configuration programming data as the programming signal to the audio processing circuit; and a bi-directional communication circuit coupled to the bi-directional input/output, including:
