Claim:
1. A method in a microphone apparatus, the method comprising: clocking the microphone apparatus using a local oscillator of the microphone; generating a digital data stream from an electrical signal representative of acoustic energy; determining whether voice activity is present in the electrical signal while buffering data representative of the electrical signal in a buffer of the microphone apparatus, the buffered data having a delay time with respect to real-time data representative of the electrical signal; providing a multiplexed data stream at an interface of the microphone apparatus after determining the presence of voice activity, the multiplexed data stream including a buffered data stream and a real-time data stream, the buffered data stream and the real-time data stream based on the electrical signal, the buffered data stream including non-real-time buffered data and real-time buffered data, an end portion of the buffered data stream temporally overlapping a beginning portion of the real-time data stream; and providing the real-time data stream at the interface after discontinuing providing the buffered data stream at the interface.
