Tim,
I agree. There are always artifacts from resampling. I didn't know those
cards did that all the time. Yuck.
In my work I never resample anything, or at least not until the final
master for the physical media is created. I always work at 44.1K, make sure
any samples and tracks others give me are at 44.1K, and make my personal
masters at 44.1KHz for auditioning where ever I need to. Only if I need a
48K for some reason do I do it then.
Cheers,
Mark
