I'm not an expert on this, but:
CD audio is 44.1kHz/16bit
If you record at anything else, you will have to downsample.

Probably, at a guess. You really want to organise things so you only
have to downsample once, as the final stage of mastering as I understand
it. This process is analogous to resizing a bitmap, you want to do all
the composition work at the highest resolution and try to avoid
resampling as much as possible.
