Remarks

Class providing information on a microphone. It indicates the location and orientation of the microphone on the device as well as useful information like frequency response and sensitivity. It can be used by applications implementing special pre processing effects like noise suppression of beam forming that need to know about precise microphone characteristics in order to adapt their algorithms.
