Systems and methods for compressing a digital signal in a digital microphone system

[0022] figure 1 A block diagram of selected components of an exemplary audio system 100 is shown, in accordance with an embodiment of the present invention. Such as figure 1 As shown, an audio system 100 may include a microphone transducer 101 , a digital microphone integrated circuit (IC) 105 and a digital audio processor 109 . Microphone transducer 101 may include any system, device, or device configured to convert sound incident on microphone transducer 101 into an electrical signal, such as an analog output signal ANALOG_OUT, wherein a diaphragm or diaphragm is used to convert such sound Converted to an electrical signal, the diaphragm or diaphragm has a capacitance that varies with the acoustic vibrations received at the diaphragm or diaphragm. Microphone transducer 101 may include an electrostatic type microphone, a condenser microphone, an electret microphone, a microelectromechanical system (MEMS) microphone, or any other suitable capacitive microphone.
