I would say that if any tool could handle it snd would be able to edit it
visually. I think snd is linux / unix only.

Also, sox should be able to split it out into individual channels or normalize
to a range other tools can use (ie. if you scale amplitude by .02 it should be
editable in a normal editor, and then sox should be able to multiply it by 50 again
when you are done -- but of course this would probably lead to some rounding errors
in quieter parts of the signal).
