Elysia calls the mpressor a “creative” compressor. Does that mean it is creative in design, or it will do creative things? Or perhaps creative in marketing?
It does have at least one really interesting feature: The auto-fast mode. Engaging this causes the attack time to respond more quickly to loud transients. UAD has emulated this, and it does what it says! The noise floor UAD chose to keep is rather interesting. (See below.) It’s probably just going to get lost in dithering (or inaudibleness*), but they modeled it anyway!
*I swear that’s really a word, look it up.
