Dynamic EQ

Overview

This processor can be very useful in controlling specific frequencies in your mix that are too loud, with a degree of precision not possible with a static EQ.

Controls

Global EQ Filter Mode

Selects the EQ processing type used for the Dynamic EQ, this setting is global and applies to all Dynamic EQ bands.

  • ANALOG: Uses a minimum-phase FIR (Finite Impulse Response) filter, which is useful in a variety of situations.
  • DIGITAL: Uses a linear-phase IIR (Infinite Impulse Response) filter, which retains the phase of the original signal, but uses more CPU.

Filter Shape

Each band of the Dynamic EQ offers the following filter shapes:

  • Baxandall Bass
  • Band Shelf
  • Peak Bell
  • Proportional Q
  • Baxandall Treble

Frequency/Gain

You can adjust an EQ band by clicking on a node and dragging it horizontally to change the frequency, and vertically to change the gain of the band.

Q (Bandwidth)

You can adjust the Q or bandwidth of any band by dragging the “handles” on the side of the node. If you have a wheel mouse, you can use the mouse wheel to widen/narrow a selected band while hovering over the node.

Threshold

Drag the threshold to adjust the amount of compression applied to the specific EQ band you have selected.

Dynamic Trigger Mode

  • UP: When a signal exceeds the threshold, the filter will move upwards.
    • If the static gain value is positive: using the Up trigger mode will move the filter from the center line toward the static node (boost when triggered).
    • If the static gain value is negative: using the Up trigger mode will apply the full negative gain until it is triggered–when triggered it will move toward the center line.
  • DOWN: When a signal exceeds the threshold, the filter will move downwards.
    • If the static gain value is positive: using the Down trigger mode will move the filter from the static boost value toward the center line (cut when triggered).
    • If the static gain value is negative: using the Down trigger mode will move the filter from the center line toward the static negative gain value.

Attack

Adjusts how long it takes a band’s dynamic trigger to react to a signal crossing the Threshold value. You can adjust the Attack value by clicking and dragging on the value readout or by double-clicking on the value readout and manually entering a value.

Release

Adjusts how long it takes for the associated band’s dynamic trigger to return the filter to the static settings when a signal falls below the Threshold value. You can adjust the Release value by clicking and dragging on the value readout or by double-clicking on the value readout and manually entering a value.

Auto Scale

When enabled, the displayed Attack & Release values are scaled automatically based on the band’s frequency value.

Offset

Sets a static gain offset for the associated band.
