FabFilter has just released a new major version of the Pro-L limiter plug-in with four brand-new limiting algorithms, a new true peak limiting mode, extensive standards-compliant loudness metering, surround support, interface enhancements and much more.

New limiting algorithms 

Pro-L 2 adds a brand-new 'best for all' Modern algorithm, together with Aggressive for EDM and rock, Bus for single-track limiting, and a new Safe algorithm that was carefully tuned to avoid distortion at all times. 

True peak limiting

The new true peak limiting feature makes it extremely easy to hit a maximum true peak target. Just set the output level to the desired value, enable True Peak Limiting: that's it!

Loudness metering

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, Pro-L 2 is the perfect fit for any loudness normalization job.
