Digilents AC97 demo, regarding the samples

badgeir · ‎11-14-2011

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!
