Abstract
A powered microphone for use with a personal computer comprising a Universal Serial Bus interface for coupling the powered microphone to a Universal Serial Bus. A circuit coupled to the Universal Serial Bus interface is configured to integrate a plurality of data streams, including clock data, digital audio data, and control data into Universal Serial Bus compatible data. A gain controller is coupled to provide control signals to a power supply and amplifier; and an audio data circuit is coupled to receive clock data and analog audio data. The audio data circuit includes an analog-to-digital converter for converting the analog audio data to a digital audio signal, and the audio data circuit is further configured to receive an audio control signal from the gain controller.
