Abstract: Systems and techniques for communicating data as a function of frequency are presented. In an implementation, a system includes a microelectromechanical systems (MEMS) sensor, a digital signal processor and a frequency detection circuit. The digital signal processor is coupled to the MEMS sensor. The frequency detection circuit receives data encoded as a function of frequency from the digital signal processor via a clock communication channel.

Abstract: A distributed automatic level control function is provided, in which information relating to a common automatic level control parameter is transmitted to each of a plurality of microphone devices, wherein the information transmitted to at least one microphone device is derived from an audio sample of at least one different microphone device. Each microphone device produces the common automatic level control parameter based on the information received by the microphone device and applies the common automatic level control parameter produced by the microphone device to a distributed automatic level controller of the microphone device.

Abstract: A throat microphone may include one or more transducers that are in contact with the skin in the region of the larynx of person, and may provide a vibration signal to a processing unit. The vibration signal may also include energy and information relating to secondary physiological phenomena such as breathing and heartbeat, in addition to the desired sonic signal. The processing unit may utilize information relating to the secondary physiological phenomena to control a filter that outputs the desired sonic signal.
