Hi, We are working on an application where we need to process the signal from 4 separate microphone channels by multiplexing the stereo ADC contained within the ADAU1761. I have a copy of SigmaStudio and have built and run successfully other DSP function and tutorial examples, but I have not been able to make the multiplexing work, specifically I have tried the example 2 in the help file. Can you advise me on how to multiplex/demultiplex with the ADAU1761, preferably with an example I can try in the SigmaStudio? Many Thanks,
