Abstract
A microphone is disclosed which converts an audio signal directly into a digital representation by analyzing and digitizing the distortion imposed upon a signal, such as a string of regularly spaced pulses as a result of the displacement of a diaphragm, relative to a sensor, in response to the incoming acoustical signal. Other devices, systems and methods are also disclosed.
