Digilents AC97 demo, regarding the samples

Hi!

I am working on a project of audio processing using the Atlys Spartan 6 board, and i am using the AC97 demo

that digilent has released.

In the demo, the samples from the AC97 is stored in Xuint32 Sample_L and Xuint32 Sample_R.

However, i have come to understand that the AC97 samples 18 bits two's compliment numbers, so I am 

wondering how the Xuint32s represent these samples?

What does the different bits represent?

As they are unsigned, 32 bit ints that is.

 

All help is appreciated!

Peter

Please do not cross-post the same topic to multiple forums.

Your other thread in the 3rd-party boards forum is the proper forum for this topic.
