A professional true peak limiter for mixing and mastering, offering eight algorithms, extensive loudness metering, surround support, and transparent sound.
Purpose and Core Design
Pro-L 2 is a peak limiter designed to maximize loudness while preserving transparency, essential for mastering and mixing. It combines multiple limiting algorithms with precise metering to help engineers achieve competitive levels without audible distortion or pumping.
The plugin includes eight distinct limiting algorithms, each with its own character, suitable for different musical material and workflow preferences. This variety allows users to match the limiter’s behavior to the source, from transparent leveling to more aggressive, characterful limiting.
Metering and Analysis
Accurate metering is a key strength. Pro-L 2 provides true peak level meters and extensive loudness metering, supporting standards like EBU R128, ITU-R BS.1770-4, and ATSC A/85. This allows engineers to measure loudness in a way that matches broadcast and streaming requirements.
A unique real-time level display shows gain reduction with peak labels and innovative display modes. The meter scale is adjustable, including K-System support, and output and gain reduction are shown with high accuracy, giving you full visual insight into the limiting process.
Processing and Flexibility
The limiter offers linear-phase oversampling up to 32x, reducing aliasing, and includes an optional DC offset filter. Intelligent channel linking allows you to control how channels are linked, with separate linking for transient and release stages, which is useful for stereo and surround material.
Surround support includes formats like Dolby Atmos 7.0.2 and 7.1.2, with flexible channel linking. External side chain triggering enables stem mastering, and an adjustable look-ahead, attack, and release gives you fine control over the envelope.
Workflow and Integration
Practical features include a Unity Gain option to hear the effect of limiting at unity level, and an Audition Limiting option to compare input and output. Smart Parameter Interpolation ensures smooth transitions when automating parameters, and MIDI Learn allows control via hardware.
The plugin supports common Pro Tools control surfaces, offers undo/redo and A/B comparison, and has a compact interface layout. A comprehensive help file with interactive hints and GPU-powered graphics acceleration round out the user experience.
