Why FabFilter Plugins Are CPU-Efficient
FabFilter plugins are among the most CPU-efficient professional plugins available. They use highly optimized C++ with hand-tuned DSP routines, zero internal oversampling by default (user-selectable), and efficient UI rendering that unloads when the plugin window is closed.
Oversampling Trade-offs
FabFilter plugins offer 2x, 4x, and 8x oversampling. Higher oversampling reduces aliasing distortion but increases CPU usage proportionally. For tracking: no oversampling. For mixing: 2x is sufficient for most cases. For mastering: 4x on critical processors (limiter, final EQ). Never use 8x unless you're doing forensic audio work — the CPU cost is rarely justified.
Pro-Q 4: New Features That Save Time
Pro-Q 4 introduced: spectral EQ mode (visualize and EQ based on the actual frequency content), instance list (see all Pro-Q instances in your session from one window), and improved dynamic EQ with side-chain filtering. The instance list alone is a workflow game-changer — you can EQ your kick drum while seeing what your bass guitar EQ is doing.
Pro-L 2: True Peak Limiting
Pro-L 2's true peak limiting catches inter-sample peaks that other limiters miss. For streaming deliverables (Spotify, Apple Music, YouTube), true peak limiting at -1 dBTP is the current best practice. Pro-L 2's different limiting styles (Transparent, Punchy, Dynamic, Allround, Aggressive, Safe, Modern) are genuine different algorithms — experiment to find which suits your material best.
