The Pro-L 2 Limiter Software Plug-In from FabFilter is a major update to the Pro-L Limiter plug-in. It adds four additional limiting algorithms: Modern for general all-purpose limiting, Aggressive for EDM and rock music, Bus specific for drums and individual track limiting, and Safe, which avoids distortion at all costs. The plug-in works for Mac or Windows computers and can be used for mixing and mastering audio applications such as studio recording, post production, and more.
Combined with true peak metering and extensive loudness metering, it is compliant with the EBU R128, ITU-R BS.1770-4, and ATSC A/85 standards. Support for surround audio with flexible channel linking makes FabFilter Pro-L 2 much more versatile in multi-channel scenarios, with up to 32x linear phase oversampling. Other features like a DC offset filter, external side chain triggering for stem mastering, and a unity gain option ensure that Pro-L 2 is a solution to any mastering challenge.
Furthermore, the real-time level display is offered with several display modes, including an infinite mode that shows all audio for an entire session. Significant gain reduction is highlighted with peak labels to give additional insight into the limiting process. The Pro-L2 interface has been carefully redesigned with an optimized workflow. Finally, the plug-in is available in VST, VST3, Audio Units, AAX Native, and AudioSuite formats, in both 64- and 32-bit, as well as RTAS in 32-bit.
