Hi-res audio folk to introduce new rules and weed out impure noises

@John Geek - what makes you think that any sampled signal is recorded with frequencies up to the Nyquist limit? That's why there are brick-wall filters on the input and a reconstruction filter on the output (and no, let's not go into the mess that a poorly designed filter can cause...)

Oversampling at very high rates has one obvious advantage: it makes the necessary pre- and post-sampling filters much easier to design and build.
