More Information
Summary:An audio synchronization processing method is provided. The method includes the following steps: receiving an input request signal; in response to receiving the input request signal, starting performing a counting operation according to a basic clock signal; outputting an output request signal according to a sampling-clock signal; in response to outputting the output request signal, stopping performing the counting operation to obtain a counting value; determining whether synchronization has been achieved based on the counting value; and in response to determining that the synchronization has not been reached, adjusting a frequency of the sampling-clock signal according to the counting value.
