Pro-G

FabFilter's Pro-G is a gate and expander plugin that ranks among the most capable dynamic processors available. Unlike basic gates that simply mute signals below a threshold, Pro-G offers six distinct algorithms tuned for different material, including upward expansion and ducking modes that expand above the threshold rather than below it. This flexibility makes it suitable for both corrective work - tightening drums or removing rumble - and creative applications like sidechain-driven pumping effects.

The plugin's real strength lies in its control architecture. Program-dependent attack and release curves adapt intelligently to incoming signals rather than applying fixed times, reducing the artificial pumping that plagues conventional gates on complex material like drums or vocals. The adjustable knee smooths transitions around the threshold, while optional look-ahead up to 10 milliseconds allows the gate to respond before transients fully arrive, preserving natural attack characteristics.

For advanced users, expert mode unlocks extensive sidechain routing options, supporting mono, stereo, and mid-side processing with external input capabilities and customizable channel linking. This depth appeals to mixing engineers handling surround work or those needing surgical control over linked channels.

FabFilter's characteristic attention to interface design shows throughout. Real-time metering displays current gain reduction and transfer curves clearly, making parameter decisions straightforward. The zero-latency operation mode and optional four-times linear-phase oversampling accommodate both tracking and mixing scenarios without compromise.

Pro-G stands as an essential tool for professionals who demand precision gating without sonic coloration or CPU burden.
