FabFilter Pro-L 2: The Mastering Limiter Pros Reach For

FabFilter Pro-L 2 has held the top spot in mastering limiters for years. Eight limiting algorithms, up to 32x oversampling for true peak control, and loudness metering that hits every modern streaming target — all in one plugin. It’s the limiter you use when you can’t afford to guess about what the master looks like on Spotify, Apple Music, YouTube or broadcast.

What’s Inside

• Eight limiting algorithms: Modern, Transparent, Punchy, Aggressive, Allround, Dynamic, Bus, and Safe — each with a distinct sonic character
• True peak limiting: final output stays under the ceiling you set, with up to 32x oversampling to catch inter-sample peaks
• Loudness metering: EBU R128, ITU-R BS.1770-4 and ATSC A/85 standards built in — no external meter needed
• Linear-phase oversampling: transparent even at aggressive settings
• Professional dithering and noise shaping: bit-depth reduction that doesn’t lose fidelity
• Surround support up to Dolby Atmos 9.1.6: intelligent channel linking preserves imaging
• Precise metering displays: peak, RMS, true peak, gain reduction, and integrated loudness at a glance

Who Is It For?

Mastering engineers use Pro-L 2 as their final limiter — the algorithms cover every genre from acoustic ballads to loud electronic music. Mix engineers use it on the mix bus during mixing to hear how the final master will behave. Podcasters and broadcast engineers use the ATSC A/85 metering to hit dialogue loudness targets legally. Sound designers on film and game teams use the immersive audio channel linking for scenes that need loudness control across surround channels.

System Requirements

• macOS 10.13 or higher, 64-bit, Apple Silicon native
• Windows 11, 10, 8 (32-bit and 64-bit)
• Formats: VST, VST3, AU, AAX, CLAP, AudioSuite

How Producers Use FabFilter Pro-L 2

Mastering engineers usually start with Modern for pop and hip-hop, then A/B against Transparent and Allround to hear which handles the specific mix best. Punchy stays exciting on aggressive rock and electronic music without smearing transients. Bus mode sits on the mix bus during mixing so producers hear the loudness the master will hit. Broadcast mixers set the true peak ceiling at -1 dBTP and check the integrated LUFS meter against the platform’s target. See our mastering plugins collection for related tools.

Frequently Asked Questions

Is FabFilter Pro-L 2 worth the money?

For anyone mastering their own music or delivering to streaming platforms, yes. The combination of eight algorithms, EBU R128 metering and 32x true peak oversampling covers every situation you’ll hit. Free limiters get you close but rarely give you the algorithm choice or metering accuracy Pro-L 2 does. Most mastering engineers who own it use it on every project.

What loudness standards does Pro-L 2 meter?

EBU R128 (European broadcast and streaming), ITU-R BS.1770-4 (international loudness measurement), and ATSC A/85 (US broadcast dialogue). That covers Spotify’s -14 LUFS integrated target, Apple Music’s -16 LUFS, YouTube’s -14 LUFS, Amazon Music’s -14 LUFS, and every major broadcast delivery spec.

Does Pro-L 2 support Dolby Atmos?

Yes — full Dolby Atmos 9.1.6 surround with intelligent channel linking. The limiter treats the front, surround and height channels as one unit so imaging stays stable when the limiter kicks in, unlike stereo-limiter-per-channel setups that shift the mix.
