Using the Block Based TalkThru example in the Analog Devices 21364 EZ-KIT

Dear comp.dsp,

I am using the ADI 21364 EZKIT Lite with Visual DSP++. I want to
implement some basic audio processing algorithms here in C.

To start, there is a "Block Based TalkThru" example, wherein I am
provided with a function which received a pointer to 1024 samples,
which are "unsigned int" values. Now, pass through works properly, but
even if I replace every sample with half of it's value, it starts
"crackling". I have tried many things, like converting it to "int",
extracting various buts etc. but in vain.

If you have seen this example, could you please tell me how to extract
the sample from the unsigned int? I could not fin this information on
ADI's website, or the documentation.

Thanks.

Kumar
