Think again. As I pointed out with simple math in a recent post, 24/96
adds about 200% wasted space to a 16/44 recording. If you are recording
stereo, this is manageable even negligible, but if you are multitracking
with a goodly number of channels, the file sizes can get to be
challenging to manage, and for what?  Numbers for the sake of numbers?

In the real world the actual performance probably has more like 65-70
dynamic range, so using 16 bits gives you 25-30 dB headroom, which any
recording engineer worth his salt can work with without problems.

Most DSP processing and editing uses 32 bits and up, so the  noise it
adds to a 16 bit context is negligible.
