Abstract:
An audio system includes an audio client device and an access point. The audio client device includes a buffer, a clock generator, a bus controller, a bus receiver, and a control module. The buffer is configured to receive a stream of samples of audio data. The clock generator is configured to generate a first clock signal. The bus controller is configured to read samples from the buffer for transmission across a bus using the first clock signal. The bus receiver is configured to receive samples from the bus controller and output a sampling clock along with each sample. The control module is configured to analyze activity of the buffer and modify operation of the bus controller to synchronize the sampling clock with a remote sampling clock. The access point includes an audio content module, a decoding module, and a network interface that wirelessly transmits the stream of samples.
