T-RackS Stealth Limiter

Best brickwall limiter on the market, bar none. I use it mainly for about 4dB of final gain. It also adds excellent glue and a bit of warmth too, if you don't push it beyond what is reasonable. I've tested every mastering limiter on the market. This buries them all... which is a bit surprising for IK Multimedia. It's a hidden gem to be sure.
