I don't *know* how the SB does the downsampling, but it would surprise
me if it wasn't done the obvious way. That is, to downsample 24/96 to
24/48, all you have to do is throw away every other sample. You're not
changing the word length, so no dithering is needed, and since the
sample rate is reduced by a factor of two, no fancy DSP is required.
That's the simple way, but not the correct way.
The correct way is first to filter it for the new Nyquist before thowing
away the samples.
