Abstract
This disclosure provides methods, systems, and apparatuses, for a microphone. In particular, the microphone includes a housing having an external device interface with a plurality of contacts including a data contact. An electro-acoustic transducer is configured to generate an electrical signal in response to sound. An electrical circuit is coupled to contacts of the interface, the electrical circuit including an ADC having an input coupled to an output of the conditioning circuit and configured to convert the electrical signal to audio data after conditioning. A controller is configured to communicate data, other than the audio data, via the data contact of the external device interface during a start-up transition period of the microphone assembly, wherein the controller is configured to communicate the audio data via the data contact of the external device interface only after the start-up transition period is complete.
