The Parametric EQ plug-in contains a graph that displays the frequency response of the EQ's processing. When editing the Parametric EQ, the graph displays the frequency response of each band as individual curves as well as a curve of the frequency response of all bands accumulated together. When profiling, the graph displays an additional curve of the accumulated frequency response of all bands including any changes to properties from RTPCs and any contributions made from the Dynamic Gain.

The graph can also be used to edit certain the properties of each band. You can enable or disable each band by double-clicking their respective control point. The control points can be dragged horizontally to control the Frequency of each band. Depending on the band's filter type, you can also drag the control points vertically to control the Gain or Q of each band. You can use the mouse wheel to zoom the graph in and out vertically, which can be used to make fine-tuned adjustments to each band.

In addition to being able to dynamically adjust properties of the Parametric EQ effect through RTPCs, the effect can also dynamically adjust the Gain of each band based on an audio signal.

When Dynamics are enabled for any band, the Parametric EQ effect either reads the specified Sidechain Mix or it uses the input audio signal itself as the Dynamics Input signal. The Dynamics Input is mixed down to a single channel of audio, run through a filter-bank based on the properties of the bands which have Dynamics enabled, and then the root mean square of each filtered band of the Dynamics Input is metered. The metered value of each band of the Dynamics Input is used to calculate a new Dynamic Gain, based on the Dynamics Threshold and Range specified for the band. Finally, this Dynamic Gain is added to whatever the Gain of the specified band is set to.

To monitor the processing for the Dynamics Input, expand the splitter to the right to view the Dynamics Input and Dynamics Gain meters. The Dynamics Input meter shows the metered result of each filtered band of the Dynamics Input. The Dynamics Gain meter shows the calculated Dynamic Gain being applied to each band.

With these Dynamics features, you can use the Parametric EQ as a dynamic EQ such as those used in some DAWs. For example, you can use these features to correct the volume of specific bands of audio when they get too loud, perform frequency-based ducking across different portions of your audio mix, or automatically apply other adjustments in order to improve the overall clarity of your mix.

The Parametric EQ effect allows for specific bands of audio to be listened to when profiling the sound engine.

You can click the Solo Band button to enable a different operating mode for the Parametric EQ effect. When Solo Band is active, the effect applies a filter on the input audio based on the properties of the active band to isolate just the portion of the audio affected by the active band and uses that as the output audio of the effect. For example, when soloing a band configured as a Low Shelf filtered with a cut-off frequency of 500Hz, the output audio is isolated to just the portion of the input audio at 500Hz and lower, and not apply any other processing to the signal. This can be used to inform what portion of the audio mix is affected by each band in the EQ.

Similarly, you can click the Solo Band Dynamics Input button to listen to one of the filtered bands of the Dynamics Input in isolation from all other processing. When Solo Band Dynamics Input is active, the effect applies a filter on the Dynamic Input audio, and uses that as the output audio of the effect. This shows what audio is driving each band of the Dynamics Input.

When the Solo Band is active, note that all other audio rendering in the sound engine is still active, as this only affects the audio processing of the Parametric EQ effect. To listen to one of the bands of audio in isolation of your entire mix, other audio busses might need to be muted or other effects might need to be bypassed.
