Chris, you raise some very valid points here. Yup, you would definitely
need some very good hi end converters for the conversion. Have always
tracked here at 24 bit 44.1. Having said that, will take a look at the
Izotope thing in Sound forge as have that here. When doing this previously,
I have used the sample conversion thing in Sound Forges processing menu but,
suspect that the Izotope method would be way better than that. Also, there
is a lot to be said for keeping all of this in the digital domain that is
assuming that they have gotten the math right. On a side note, have
personally always been happy with Sonar's PowR3 dither and think it does a
better job than Sound Forge.

Wow, you prefer this method to using a sample rate converter like that found
in Sonar or the iZotope SRC with newer versions of Sound Forge? The ADC and
DAC in both PC's had better be high quality, not to mention the analog
circuitry in both audio interfaces had better be quiet, or you're degrading
things just by doing things in analog - possibly adding jitter and
increasing the noise floor. Not to mention, you have to do this in real
time.
Personally, I load the file into Sound forge, go into iZotope 64-bit SRC,
and bump it's quality setting up to 100. If you don't want to bother
adjusting all the parameters available, check the box that says Use
Simplified Interface, and then just set the sampling rate and quality
setting. If converting like that is adding aliasing or other artifacts, I
definitely can't hear them.
