PSP Twin-L is a dual algorithm classic limiter. The aim of this plug-in is to provide a wide variety of shaping options. The plug-in is able to emulate the main features of two types of limiter: VCA-limiters, which is a modern type of analog limiter, and Opto-limiters which are vintage optical limiters. Keep in mind, however, that PSP Twin-L’s limiting algorithms are not intended to emulate any specific hardware but rather to bring the capabilities of both types into a versatile plug-in. It’s also worth mentioning that the PSP Twin-L is part of our series Zero Latency Processing plug-ins; no additional latency is critical in many situations such as live monitoring and managing automation.Requirements:PC• VST• Windows x32 or x64 (XP Service Pack 2, Vista or 7)• VST 2.4 compatible application• RTAS• Windows x32 or x64 (XP Service Pack 2, Vista or 7)• ProTools LE 8.0.0 or ProTools TDM 8.0.0 (or later)Mac• AudioUnit• Mac OSX 10.5 or later• 32 or 64-bit host application capable of running AudioUnit plug-ins with Cocoa view• VST• Mac OSX 10.5 or later• 32 or 64-bit VST 2.4 compatible host application• RTAS• Mac OSX 10.4 or later• ProTools LE 8.0.0 or ProTools TDM 8.0.0 (or later)
