anyone to offer csound perceived volume maximizing orc sco?

or better yet, an opcode?

amplitude. not csound crap but a universal problem. simply a simple matter
that isn't. and just when you think you have it under control, you create a
maxed out (32767) sound of minimum volume. with no hidden "loud"
frequencies above and below pitches audible to humans to confuse the
hardware. keep in mind that i am not talking about a long file with a
single transient hiding somewhere -just a single second or so of sound that
i just can't seem to crank up. and this happens far too frequently.

their are commercial products out there designed to increase perceived
volume of sounds that are otherwise maxed out. masterlist cd (for use with
digidesign products -a cruise of their ftp turned up an empty detailed info
folder) allegedly has a killer feature for maximizing files, and i believe
sonicworx.

have been told that some such features rely on complex algorithms to select
and limit certain frequencies while increasing volume of others to increase
overall perceived volume with minimum detrimental effect.

in fact my sense is that the professional audio industry frowns on
normalizing in general even at 90% though i personally don't encounter
problems that would become apparent if i was dealing with realistic human
voices, violins and such. and compression coupled with an increase in gain
is a solution even worse in for those purposes.

so does anyone have a handy dandy magic bullet at the ready for this in
csound, or other shareware or do i take out my credit card yet again? and
if yes on the credit card, what do our best and brightest recommend?

assistance or advice extremely appreciated.
