Description
Blue Cat's Triple EQ is a 3-band semi-parametric equalizer from Blue Cat Audio that behaves like a single shapeable filter. It combines a low shelf, a high shelf, and a peak filter, with all three bands linked so adjusting the center frequency or bandwidth moves every filter in lockstep.
Each band offers an unusually wide gain range of +/-40 dB and bandwidth from 0.01 to 5 octaves. This makes it capable of anything from subtle tonal adjustments to dramatic filtering effects, all displayed on a real-time frequency response graph.
The plugin ships with a dual-channel mode for independent left/right or mid/side equalization, which users on Gearspace and Reddit highlight as one of its most practical features. Multiple linking modes let you turn it into a frequency-dependent panner or stereo shaping tool.
All parameter changes are completely zipper-free with zero latency, making it well-suited for real-time MIDI control and automation. Full MIDI Learn support and smooth bypass ensure clean transitions during live performance or mixing.
Blue Cat's Triple EQ supports VST, VST3, AU, and AAX formats on both macOS and Windows, including native Apple Silicon support. It uses no CPU when fed silence, making it efficient enough to load on every track in a session.

Frequently Asked Questions
What makes Blue Cat's Triple EQ different from a standard parametric EQ?
Unlike a typical parametric EQ where each band is adjusted independently, Blue Cat's Triple EQ links all three bands together so they move as one shapeable filter. Changing the center frequency or bandwidth adjusts all three filters simultaneously, which makes broad tonal adjustments faster and more intuitive.
Can Blue Cat's Triple EQ do mid/side processing?
Yes. The dual-channel version included with the plugin offers independent left/right or mid/side equalization. Multiple channel-linking modes also let you use it as a frequency-dependent panner for creative stereo effects.
Does Blue Cat's Triple EQ introduce any latency?
No. The plugin operates with zero latency and all parameter changes are zipper-free, meaning you can automate it or control it via MIDI in real time without any audible artifacts or delay compensation issues.
How does Blue Cat's Triple EQ compare to FabFilter Pro-Q?
FabFilter Pro-Q offers more bands, dynamic EQ, and a spectrum analyzer, making it better suited for surgical mixing work. Blue Cat's Triple EQ focuses on fast, musical broad-stroke equalization with its linked three-band design and mid/side capabilities, serving a different workflow.
