Not only is there significant additional noise
and distortion upon ampification, the ability to
use equalization processing to good effect is
significantly reduced if working with 5 opposed
to 8 bits of data. I suspected this for seveal
years and finally made up clips with a range of
low saturations to test. I recall there was a 6dB
increase in broadband noise above 2k between 1%
and 3% saturation for example.

You're right, a raven calling as he flew right
over the array in the same forest produced 3
clipped samples. Drats! I lost 1/16,000 of a
second. I do appreciate the overhead but the
dynamic range in quiet natural settings here in
the upper mid west is safely within 24dB, barred
owls directly overhead included. I do fear losing
a close coyote chorus someday, but in the
meanwhile I'll get the others with extra bits.
