I agree with Paul Stamler that the best approach to sample rate
conversion is to avoid it. It seems that there are good SRC processes
and not-so-good ones, just like there are good and not-so-good D/A and
A/D converters, and good sample rate conversion requires a lot of
computer horsepower. You have to, in essence, reconstruct the original
waveform of the source, then re-sample the (virtually) reconstructed
waveform at your desired rate. If the reconstruction isn't accurate,
you'll end up re-sampling interpolated values, and that's what doesn't
sound right.
A while back, someone, maybe it was Mytek, made a converter that could
use separate clocks for the D/A and A/D sections, so you could just pipe
the output into the input and convert the sample rate in a single
hardware box. It sounded better than any of the software SRC programs of
its time. But then, Mytek's converters were among the best sounding ones
in the industry, so they had a good start.
