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.

Distributed automatic level control for a microphone array

A data communication system has a number of communicatively coupled devices, including at least one slave-only device. Techniques for use in the data communication system include techniques for synchronization and re-synchronization of frame and bit clocks, techniques for assigning device address, techniques for dynamically controlling transmit power based on the number of devices, and techniques for serialized signal processing.

Synchronization, re-synchronization, addressing, and serialized signal processing for daisy-chained communication devices

A simplified bus arrangement using only three signal lines allows TDM data to be conveyed to or from a number of slave-only devices without the use of separate command line(s) and without any of the slave-only devices having to operate as a bus master or even support a master operating mode.
