When I resample CD audio for use in DVD production (which
needs to be 48k) I can here noise in the wav file that
wasn't there when it was 44k. I know this has to have some
thing to do with resampling the file at a higher sample
rate, but is there anyway to get a clean resample without
the noise? I have tried noise reduction but I havn't had
great results. Thanks in advance.

What sound card are you using?

On my system if I don't change the clock from 44.1 to 48 on my DSP
Factory I get noise on playback. Make sure that your sound card
sample rate matches your .wav files. This seems to only be an issue
in SF as Acid and Vegas will convert on the fly.
