I just had a look on the Wolfson product page, the WM9711 is an AC97 codec -
so it converts between analogue and digital audio -
http://en.wikipedia.org/wiki/AC97 for a better explanation. You'll have to
see what else it could be connected to - as I understand it, a DSP will
usually be used to provide the AC97 signal (which could be a separate device
or integrated into the main processor.)

Hope this helps,

Bryn
