Abstract
An audio system may include a microphone configured to sense sound and generate an analog audio signal; an analog-to-digital convertor (ADC) configured to convert the analog audio signal to a digital audio signal having a first bit rate; a motion sensor configured to sense motion associated with the microphone and generate a motion signal representative of the motion associated with the microphone; a motion signal conversion module configured to convert the motion signal to a digital audio noise signal having a second bit rate synchronized with the first bit rate; and a noise suppression module configured to at least partially suppress the digital audio noise signal relative to the digital audio signal to generate a noise-suppressed digital audio signal.
