Thank you for your replies. I have read the datasheet WM8731.

The AUD_ADCDAT is the audio data... but may i know the result is it a numeric value? I am still blur with how can i get the sound data as in using wavread function in MATLAB.

Like if i m sampling at 8000Hz, i will have 8000 samples. How can i allocate this 8000 samples for FFT analysis?

Please advise again. I am totally a newbie. I would like to learn.

Many Thanks.
