@ Stereo Tool... it's a bit antiquated in design. It'll get you about up to the Optimod 8100A1/XT2 days, circa 1985... but it can't emulate what the new boxes sound like, yet. I won't go into the technical history of broadcast processing from 1985 till now to prove it (in this topic at least), but its out there for those willing to geek out hard enough and talk to some insiders along the way. By nature it is an industry of secrets, much like mastering can be, so you might find it hard getting more than a general overview.
What you could do is compare what Stereo Tool sounds like quasi-on-air against a good sounding local station, with something like MPX Tool, or some other modulation monitor that doesn't let you (or them) cheat by over-modulating. You'll get the picture pretty fast that Stereo Tool is obviously a great value for the price, but can't hang with the big boys.
If you're just using it to get a general idea of what *might* happen to your music when it gets played on air (which is all you can do) then it's a pretty good tool for that IF there is a preset that sounds very average in comparison to stations across your target areas (be it 75uS or 50uS emphasis).
Oh and... PMs sent.
