FabFilter Pro-DS is an intelligent de-esser plug-in designed to deliver transparent and effective vocal sibilance control. It features a unique Single Vocal detection algorithm that accurately distinguishes sibilance from non-sibilance in individual vocal tracks, streamlining setup without complex adjustments. For broader applications, the classic Allround detection mode provides a finely tuned side-chain filter ideal for processing full mixes or applying high-frequency limiting to various audio material.

The plug-in’s interface offers intuitive controls and detailed visual feedback, making it simple to dial in precise settings quickly. A large real-time level display highlights the sections affected by de-essing, while a circular side-chain input meter assists in selecting the optimal threshold. Additional features include a real-time spectrum analyzer within the side-chain filter controls and GPU-powered graphics acceleration, ensuring smooth animations and efficient CPU usage during processing.

FabFilter Pro-DS also supports advanced processing options such as adjustable look-ahead timing, stereo linking, and mid/side processing for selective audio channel treatment. Users can choose between wide-band compression or linear-phase split-band processing, with up to four times oversampling to achieve highly transparent results. These capabilities, combined with its user-friendly design, make Pro-DS a powerful solution for precise de-essing in both mixing and mastering environments.
