Abstract: In accordance with an embodiment, a method of producing a TDM serial audio stream includes: receiving a plurality of input audio signal streams from an audio source clocked at an input clock frequency and producing therefrom a TDM serial output stream clocked at a TDM output clock frequency; obtaining the input clock frequency and the TDM output clock frequency by dividing a master clock frequency; writing audio signal samples from the input audio signal streams into a set of memory buffers at the input clock frequency; and producing the TDM serial output stream from audio signal samples buffered in the memory buffers by reading the buffered audio signal samples at the TDM output clock frequency.
