FabFilter Pro-L 2 Limiter Audio Plug-in Software

Musical and precise, from individual tracks to full surround-sound mixes, the FabFilter Pro-L 2 limiter uses a unique real-time display for a quick workflow.

Pro-L 2 is a major update to the Pro-L limiter plug-in. With four 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. Also added is the true peak limiting mode which makes it extremely easy to hit a maximum true peak target. Combined with improved true peak metering and extensive loudness metering that's compliant with the EBU R128, ITU-R BS.1770-4, and ATSC A/85 standards.

Complete support for surround audio with flexible channel linking makes Pro-L 2 much more versatile in multi-channel scenarios, while the sound quality is even higher than before with up to 32x linear phase oversampling. Features like a DC offset filter, external side chain triggering for stem mastering, and a Unity Gain option ensure that Pro-L 2 is the solution to any mastering challenge.

The unique real-time level display is even more effective with innovative display modes, including an Infinite mode that shows all audio for an entire session. Moments of significant gain reduction are highlighted with peak labels to give additional insight in the limiting process. The interface has been carefully redesigned to be aesthetically pleasing with a perfectly optimized workflow.
