Abstract
The present disclosure describes a wireless microphone system that allows one or more microphones to wirelessly communicate with a receiver. Additionally, the wireless microphone system may allow for a plurality of microphones to be used interchangeably with the receiver. To ensure communication between the receiver and the one or more microphones, the receiver may occasionally transmit a synchronization signal to the one or more microphones. In response to receiving the synchronization signal, at least one of the one or more microphones may determine that a clock of the at least one microphone is drifting from the master audio clock of the receiver. The at least one microphone may then adjust the microphone's audio clock to re-synchronize the audio clock of the microphone with the master audio clock of the receiver.
