ABSTRACT:
A method and apparatus for synchronizing AES digital audio signals for switching clocks each signal into a respective buffer under control of a recovered clock from each signal. A sync detector for each signal identifies a synchronizing symbol and enables the loading of the corresponding buffer starting with the synchronizing symbol. A common clock is applied to all of the buffers starting with a system sync signal to read out all of the buffers simultaneously in synchronization with each other so that when switched, there is no corruption of the output AES digital audio signal that might cause a "pop" to be heard.
