Our verdict on FabFilter Pro-L 2
FabFilter Pro-L 2 is a professional true-peak limiter plug-in for mixing and mastering. It is aimed at mastering engineers, mixing engineers, music producers, and other audio professionals working with mono, stereo, surround, or immersive audio. The plug-in runs on Windows and macOS in VST, VST3, Audio Units, CLAP, AAX Native, and AudioSuite formats, while the iPad version is available as an AUv3 effect. It supports common hosts including Pro Tools, Studio One, Logic Pro, Ableton Live, and Cubase.
Its strongest area is control over limiting and loudness. Eight limiting algorithms provide different processing approaches, while true-peak limiting, loudness metering, configurable targets, and support for EBU R128, ITU-R BS.1770-4, ATSC A/85, and TR-B32 address delivery-focused workflows. Up to 32x linear-phase oversampling, three dithering noise-shaping algorithms, MIDI Learn, A/B comparison, and undo/redo add useful depth for detailed mastering decisions. External side-chain triggering also supports stem mastering workflows.
Pro-L 2 is particularly well suited to projects that extend beyond conventional stereo mastering. Surround and Dolby Atmos processing up to 9.1.6 makes it a fit for immersive production, while its broad desktop plug-in support helps it fit established DAW-based workflows. The iPad app adds an AUv3 option, with the listed US App Store price at 39.99; desktop pricing may vary by currency or region. Choose it when precise limiting, metering, oversampling, dithering, or immersive support matters. Those seeking a free tool or a standalone mastering application should choose an alternative.
