Re: [Avid-L2] Re: Audio dynamic range

Ii was definately over-thinking this one. As mnay suggested, I simply
put on the digi compressor, opened the threshold all the way, set the
compression settings very mildly, and flattend the knee completely.
Also had to add gain, of course, because low sounds were higher, but
high sounds were lower. Worked great, no obvious breathing or anything.
