Hi Phil, Amadeus will down-sample to the format you're pasting to. I suppose it's possible that some aliasing issues could occur and people might suggest you do the original recording at the same bit rate and depth, but I doubt the human ear will hear much discernible difference. From what I've read, there's no advantage in recording at a higher sampling rate and bit depth if you know the final product is going to be down-sampled, unless of course you keep the original recordings for use at the original specifications at some future time when technology has moved on a bit. To that extent, recording at the maximum possible sampling and bit depth is kind of future-proofing you, if you're going to hang on to those original recordings.
