FabFilter Pro-L 2 Limiter Software Plug-In

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.
