FabFilter Pro-L 2

A pro-tier brickwall limiter aimed squarely at mastering, with true-peak handling and loudness work suited to Dolby Atmos delivery. It runs as VST3, AU, or AAX across Windows and macOS. This is for engineers doing serious mastering and standards-compliant loudness; if you only need a basic ceiling on a mix bus, it's more limiter than the job requires.
