What X-DynEQ does

Rather than applying a fixed boost or cut, each band reacts to changes in the amplitude of the audio that passes through it, so it can sculpt an instrument, a vocal or a complete mix only when the material needs it.

The plugin is organized around a node-based interface in which each band is a node placed on a frequency display. Nodes are created by double-clicking, and keyboard and mouse-wheel shortcuts adjust them. When a node is switched to dynamic mode, its Attack, Release and Threshold parameters become active. A piano roll view helps visualise and navigate the filter cutoffs and centers. An optional HQ mode uses SSL’s anti-cramping technology.

Key features

• Automatic dynamic options. Auto Attack and Release Threshold options set the dynamic timing of a band without manual adjustment, which streamlines the workflow for dynamic EQ use.
• Per-band stereo processing. Each band has advanced controls that process the stereo, left, right, mid or side signal separately.
• Advanced sidechaining. Each band can route an internal or external sidechain signal, and dynamic nodes can be sidechained from any other node or band for precise equalization.
• Preset compatibility. Presets from X-EQ 2 are translated when they are loaded, which protects earlier work.
• Built-in help. An integrated help function gives immediate assistance and shortens the learning curve.
• Crack, keygen and serial variants. Search queries for the plugin often pair its name with keygen, serial key and crack, and the Windows and macOS builds are listed under those terms.

Use cases

• Taming resonances in a mix. Dynamic bands can cut a frequency only when it exceeds a set threshold, which suits resonances that appear on some passages and not others.
• Shaping a mix bus. Sidechained dynamic nodes can respond to a band elsewhere in the spectrum, so one part of the mix can make room for another.

Compatibility

The plugin comes as VST3, VST2, AU and AAX for Windows 10 and macOS 11 in 64-bit builds, with native support for Apple Silicon listed.

Who it is for

The plugin is aimed at mix engineers and producers who want frequency-specific control that responds to level changes, and at users moving presets from X-EQ 2.
