Barricade Pro
Key Features
- Multi-factor limiting across four simultaneous domains: waveform (soft clipping), envelope, loudness (RMS), and stereo correlation
- Inter-sample peak (ISP) protection to catch peaks between digital samples and prevent distortion on playback
- Professional Bob Katz K-System metering with switchable K12, K14, and K20 scales for broadcast, CD, and DVD mastering standards
- Adjustable soft clipping with dedicated threshold and amount controls for analog-style warmth and saturation character
- Stereo correlation limiter that independently tames the side signal to prevent phase cancellation during aggressive limiting
- Dithering and perceptual noise shaping for bit-depth reduction when preparing final masters at lower bit depths
- Internal 64-bit audio processing with support for sample rates up to 196 kHz
Description
Barricade Pro by Jeroen Breebaart is a multi-factor limiter that processes audio in four separate domains simultaneously: waveform limiting (soft clipping), envelope limiting, loudness (RMS) limiting, and stereo correlation limiting. This multi-layered approach gives mastering engineers surgical control over dynamics that most limiters simply cannot match.
Each limiting section has fully adjustable time constants and thresholds, letting you dial in exactly how aggressively each domain responds to incoming audio. The waveform limiter introduces gentle soft clipping for a warmer, analog-style ceiling, while the envelope limiter handles classical peak reduction.
The RMS limiter controls sustained loudness independently from transient peaks, and the correlation limiter tames the stereo side signal to prevent phase issues during heavy limiting. An inter-sample peak (ISP) control catches the hidden peaks that occur between digital samples, a feature typically reserved for premium commercial limiters.
Barricade Pro includes professional metering based on Bob Katz's K-System, with switchable K12, K14, and K20 scales alongside digital peak, peak hold, RMS, and correlation readouts. Output bit-depth can be reduced using dithering and perceptual noise shaping for final delivery.
The plugin supports sample rates up to 196 kHz and processes 64-bit audio data internally. On KVR Audio forums, users describe it as an "uber-clean surgical limiter" best suited for mastering rather than mixing, praising its transparent limiting and detailed parameter control.

Frequently Asked Questions
What are the four limiting domains in Barricade Pro?
Barricade Pro operates across waveform limiting (soft clipping), envelope limiting (classical peak reduction), loudness/RMS limiting (sustained level control), and stereo correlation limiting (side signal taming). Each domain has independent time constants and thresholds, so you can fine-tune how each responds to your audio.
What is the free alternative to the Waves L1 limiter?
Barricade Pro is a strong alternative to the Waves L1 for mastering. While the L1 is a straightforward brickwall limiter, Barricade Pro offers four simultaneous limiting stages plus inter-sample peak protection and K-System metering, giving you more detailed control over the final master.
Which is the best mastering limiter?
The best mastering limiter depends on your workflow. Commercial options like FabFilter Pro-L 2 and Sonnox Oxford Limiter are industry standards. Barricade Pro competes with these by offering multi-factor limiting, ISP control, and professional Katz metering at no cost, though it is limited to Windows 32-bit VST.
Does Barricade Pro support macOS or 64-bit hosts?
No. Barricade Pro is a 32-bit Windows-only VST plugin. It will not run natively on macOS or in 64-bit-only DAW hosts. You can use a 32-to-64-bit bridge like jBridge on Windows to load it in modern 64-bit DAWs.
