Only amongst the cliquish brotherhood of music audio engineers.Glen, I finally understand your definition better from that last post. It's also in line with Chibi's algorithm. Most people use parallel comp and upward compression interchangeably.
That's not *my* definition of upward compression, that is *THE* definition of upward compression in general and understood much easier in just about any engineering field dealing with analog signal processing and analog information theory outside of the relatively small one of audio engineering.
But unfortunately, in audio engineering folks have become so biased into thinking that "compression" means downward compression that they try to find Rube Goldberg ways to use downward compression to synthesize everything. Hence the belief that parallel compression is really upwards compression, because that's what a few name brand engineers called it in an originally slang-ish way because it kinda sorta resembled a form of real upwards compression.
Again it's just like "normalization", where a colloquial use of the term common strictly to our narrow little racket has led folks to believe that "normalization" means something close-to-but-not-quite-really what it actually does mean. (And don't even get me started on "phase inverter" switches on track channel strips

Yeah, to a degree it's just semantics, but on the whole it's more than that. These colloquial "slang" uses of otherwise common engineering terms lead to misunderstanding and miseducation of the real mature of what's going on.
