Yeh, they make a big deal about Stealth's superior ISP detection. I'm skeptical, though. To do "true" peak detection properly is very CPU-intensive and not practical in a real-time processor. In all likelihood they're doing the same thing everybody else does, which is to use 4x or 8x oversampling. it's not going to be 100% accurate but it's close enough and requires far less number-crunching.
It is oversampling, not true peaks. You can set it to either off, 4x or 16x in the plugin. It notes which you are using, and notes it as intersample peak detection.
That part of it isn't notable, same deal you see in many plugins as you note (I think of the ones I play with only Tone Booster Barricade actually has a lookahead setting). The big deal is the damn thing works like a volume control up to like 9dBish of boost. I dunno how it does it, but it really does seem to just make everything louder, with no changes to sound character. Any others I've tried only were able to do very small boosts, if at all, before either the character of the sound started changing or they started to distort in some way. This thing does distort/sound bad if you push it too hard but you can damn near double the perceived volume and have it sound the same as it did before. Even things like drum transients. Obviously they get reduced but they don't sound reduced, the hits still hit.
I figure it is a demonic pact, or gremlins or some such, but whatever, I'm happy :D.
