No license keys or activation codes are included, as distributing such material would violate copyright and software‑licensing terms.) | Aspect | Details | |--------|---------| | Type | Parametric/linear‑phase EQ with up to 24‑band dynamic processing | | Platforms | macOS (AU, VST, VST3, AAX), Windows (VST, VST3, AAX) | | CPU | Very low‑latency native mode; moderate CPU in linear‑phase mode (depends on band count) | | Key Features | • 24 EQ bands (including 8 dynamic bands) • Real‑time spectrum analyzer with selectable resolution • Adaptive & dynamic EQ curves (side‑chain capable) • New “Zero‑latency” mode for live‑performance use • Intelligent “Auto‑EQ” suggestions (via FabFilter’s “Auto‑EQ” assistant) • Fully resizable UI with dark/light themes | | Typical Use Cases | Mixing/mastering, post‑production, sound‑design, live‑sound monitoring (zero‑latency mode) | 2. Sound‑Quality & Workflow | Category | Evaluation | |----------|------------| | Transparency | The linear‑phase mode is truly transparent up to the Nyquist limit, with negligible phase coloration. In zero‑latency (IIR) mode the plugin behaves like a high‑end analog‑style EQ, which many users love for its musicality. | | Dynamic EQ | The 8 dynamic bands can be triggered by the input signal or an external side‑chain, making it possible to tame resonances, de‑ess, or perform frequency‑dependent compression without a separate compressor. The envelope follows are smooth and musically responsive. | | Spectrum Analyzer | The integrated analyzer offers up to 8192 points of resolution and can be set to “Linear”, “Log”, or “Octave” scaling. Real‑time display is lag‑free even with 24 active bands, which is a huge help when making precise surgical cuts. | | Interface | Drag‑and‑drop band creation, easy mouse‑wheel fine‑tuning, and “Snap to” options (including musical pitch and dB) speed up workflow dramatically. The UI scales cleanly on high‑DPI monitors. | | CPU Impact | In native (IIR) mode, even with 24 bands the plugin typically uses < 5 % of a modern CPU core at 44.1 kHz. Linear‑phase mode can climb to ~15‑20 % with a full 24‑band load, but this is still well within the range of most DAWs. |
