please explain what peak slammer does ?.
there are several facilities in rpr, some are vst that can be used in other packages.
mebe check out reacomp, event horizon, major tom. Stillwell Audio - It’s About The Sound » Home
u might ask for info regarding the two latter as to whether they meet
your needs. and cockos.com re reacomp.
cos i dont wanna mislead you.
in each are quite a few parameters one can adjust.
but whether they meet your needs...mebe just try the demos ?
i know for myself i get things pretty "hot" lol.
while at the stillwell site also notice the spectro n vibe eq plug ins.
some folks find these rather interesting , and u might find a use for em on some things. dunno .
