Method and apparatus for audio receiver clock synchronization

摘要

An audio receiver's output clock is synchronized based on a number of input and output audio samples measured over a predetermined sample period. In one embodiment, a sample difference may be determined by subtracting the measured number of input audio samples from the measured number of output audio samples. This sample difference may then be compared to a predetermined threshold. In one embodiment, if the absolute value of the sample difference is less than the predetermined threshold, no adjustment to the output clock may be needed. When the absolute value of the sample difference is greater than the predetermined threshold, the output clock rate may be adjusted either upwards or downwards.
