A method for determining a displacement offset of a voice coil of a speaker, comprising: providing a drive signal comprised of a program content signal and a test signal to the voice coil of the speaker; determining at least one value representative of an impedance of the voice coil according to a voice coil voltage and a voice coil current, wherein the voice coil voltage and the voice coil current result from, at least, the test signal; determining whether the at least one value indicates that an offset displacement of the voice coil exceeds a predetermined offset distance; and reducing a magnitude of the drive signal provided to the voice coil if the at least one value indicates that the offset displacement of the voice coil exceeds the predetermined offset threshold.
Systems and methods of wirelessly connecting devices that include detecting a physical contact with a peripheral, such as by a double-tap contact with the peripheral, in response to which the peripheral wirelessly connects to a nearby device.

DIGITAL SIGNAL PROCESSOR/NETWORK SYNCHRONIZATION FOR PROCESSING AUDIO DATA
A system for synchronizing a local audio processing clock rate of a digital signal processor (DSP) to an audio clock rate of a network to which the DSP is connected. The system includes an adjustable clock synthesizer that is configured to establish the local audio processing clock rate of the DSP. The DSP is configured to generate events that are associated with the local audio processing clock rate of the DSP. The DSP is further configured to monitor the generated events over time and based on the monitored events cause the adjustable clock synthesizer to adjust the local audio processing clock rate of the DSP to better match the network audio clock rate.
