FabFilter Pro-G is a dynamic gate and expander plugin designed to enhance audio tracks with precision and character. Featuring five carefully crafted algorithms, including classic analog models and specialized settings for vocals and guitars, it allows smooth processing of drum and vocal tracks. Adjustable parameters such as threshold, ratio, range, and timing controls provide detailed shaping of dynamics, making it equally effective for subtle restoration during mastering.

The user interface of Pro-G emphasizes clarity and ease of use, with a real-time level display that combines input, output, and gain reduction meters for immediate visual feedback. This intuitive design, complemented by transfer curve and threshold indicators, simplifies the process of selecting optimal settings. Whether you are fine-tuning a gate or setting up an expander, the interface supports efficient workflow without overwhelming the user.

An Expert mode expands functionality by revealing advanced side-chain routing, filtering, and wet/dry controls, allowing in-depth customization for complex mixing scenarios. The plugin supports mono, stereo, and mid/side processing, along with MIDI triggering and zero-latency operation. Pro-G also includes multiple presets and typical FabFilter features like smooth parameter transitions, undo/redo, and sample-accurate automation, all while maintaining low CPU usage for seamless integration into any production environment.
