Abstract
Various embodiments describe techniques for switching microphones in a multiple microphone system. The techniques incorporate sampling audio signals from multiple microphones, determining a microphone that has the greatest incoming amplitude during the analysis window, and switching the microphone to that greatest amplitude microphone. The transition point for switching microphones may be determined when either the amplitude of the incoming signal is within an error bound of zero or at a 'zero-crossing' in the input amplitude stream.
