i think, recording at low level, you are kind of "loosing disc space".
lets say, if you are recording at 24bit, on low level the signal
information will take only 12 bit (example) and the rest of 12 bit will
be only empty data information.
don't think that one can repair that with some gain plugin or

If you think about this for a couple of seconds, you may
decide to reformulate your opinion. In a low-level signal,
you say the "top" (Most Significant) bits will be zero. In
a high-level signal, though, the bottom 12-bits are all ones.
What is the difference?

In the computer, a signal is a signal, regardless of the
value at which it is represented. It is only when you try and
look at the distance from that signal to either the noise floor
or the max, or deal with non-linear perceptual effects (equal
loudness curves, etc.) that level may come into play.

It's not the absolute level that matters, it's the dynamic
