How about if the project was also using loops recorded
at 44.1 kHz?
If
the Ardour project is at 48 kHz, the loops would need to be
up-sampled,
and then the whole thing down-sampled again to 44.1 on export. Would
that up-down sampling offset any benefit of using 48 kHz in the first
place?
Hey, how about resampling them up, do everything you wanted to do with
the rest of the song, stripping the loops out, downsample the song,
adding the *44.1*-samples, and finish off the mix.
Go!
