Dynamic EQ: Precise Control, Exactly When It Matters (VST3 / AU)

The Story

Welcome to Dynamic EQ. This plugin combines precise static tone-shaping with per-band dynamic (level-triggered) gain control, real-time problem-frequency detection, and a freehand curve-drawing workflow, all inside a single 8-band equalizer.

Designed for engineers who want the speed of a modern EQ without giving up the control of a true dynamics processor, it bridges the gap between everyday corrective EQ and dedicated multiband dynamics tools. It began life as a Max for Live device and has been rebuilt as a native C++/JUCE plugin so it runs directly inside Cubase, Studio One, Logic Pro, and any other VST3/AU host, without needing Max for Live installed.

Unlike a plain static EQ, every band can be told to only engage once the signal crosses a threshold you set. By separating the static shape from the dynamic behaviour, you have surgical control over exactly when and how much any given frequency region moves — whether you're taming a resonance that only flares up occasionally, de-essing a vocal, or carving space for a kick drum only while it's actually hitting.

What You Get

• The Dynamic EQ Plugin: Native VST3, AU formats.
• The Comprehensive User Manual (PDF): A deep-dive guide covering the interface, the dynamic EQ engine, resonance and clash detection, and practical mixing/mastering recipes.

Key Features

• 8-Band Engine: Dedicated Low Cut and High Cut filters plus 6 fully parametric bands (Low Shelf / Bell / High Shelf).
• Per-Band Dynamics: Independent Threshold, Range (±48 dB), Attack, and Release turn any of the 6 parametric bands into a true dynamic EQ, with both downward (compressive) and upward (expansive) behaviour.
• Internal & External Sidechain: React to a band's own filtered signal, or route in up to 6 external sidechain sources (SC1–SC6) so one track's dynamics can be driven by another entirely.
• Resonance & Clash Detection: Surface problem frequencies on Internal sidechain, or find exactly where two sources are masking each other on an External source.
• Stereo, L/R, and Mid/Side Routing: Process the full stereo signal, a single channel, or the Mid/Side components independently on every parametric band.
• Draw / Sketch Mode: Freehand-sketch a target curve and have it automatically matched onto real bands.
• Summed View: Monitor the true combined Left/Right output plus Mid/Side ghost curves before committing to changes.
• Real-Time Spectrum Analyzer & Autogain: A fixed-scale FFT overlay with peak-hold, plus deterministic, curve-based level compensation for reliable A/B comparisons.
• Modern resizable UI.
• Known limitations:

  • In Logic Pro, it's not possible to add Dynamic EQ to a mono track (workaround: record a mono track and then switch it to stereo);

  • In Logic Pro, direct clicks on the panel arrow icon may not register (workaround: click anywhere along the horizontal strip containing the arrow, or use the Down Arrow / Up Arrow keys);

  • In Ableton Live, only the active parameter is visible for automation (workaround: use the Max for Live version of our Dynamic EQ);

  • Your DAW should support multi-sidechaining to use all 6 external sidechain sources.
