Graphic EQ | Virtual View - AVX Architect
This video covers the Graphic EQ object in the Virtual View of AVX Architect, part of a series on audio processing objects. You’ll learn Graphic EQ-specific terminology, explore its factory panel, see where to find it in the Virtual Library, and learn how to add it to your workspace for system design.

. In this video, we’ll continue to explore the Virtual View of AVX Architect and look at the Graphic EQ object.
The Graphic EQ is found in the virtual view, under the “Equalization” section of the audio processing objects. The Graphic EQ allows you to boost or cut predetermined frequency bands. In the Graphic EQ window, we can see the specific frequency points listed here on the bottom of the sliders. The frequency points can be boosted or cut by clicking and moving the sliders, or incrementally by pressing the bump up or down buttons.
Below the frequencies, the “Enable” button will turn on the EQ processing and will affect all signals passing through the Graphic EQ. Pressing the “Flatten” button will set all filters back to 0, clearing any changes that have been made. The bandwidth, or Q, of all the filters can be set using this drop-down between broad and narrow filters.
At the top of the window, we see the object label name in the top-left corner. Here in the right-hand corner, there’s the lock button. When the lock button is red, the sliders and parameters on this control panel are locked and cannot be changed. This button next to the lock button is the Selection mode switch. Turning Selection mode on allows us to select various parameters and copy them if we wanted them in a custom panel.
In the Properties window, we can name the processing object, which will appear above the object in the workspace. The name and type displayed above the object in the workspace can also be hidden by unchecking these “Show” checkboxes. “Coordinates”, is showing us where in the workspace this object is, and “Size” is the object box size in the workspace. These can also be changed by dragging the object around in the workspace or grabbing the handles to resize. “Allocation” identifies the DSP in the system where this processing object resides. With multiple DSPs, you can choose the DSP where this processing will occur.
Under the “Options” section, we can change the number of channels on our object block. The value can be typed directly in. The lowest number is 1, and the highest number is 512, as is common with many of our processing objects. Finally, the number of bands for the EQ is selected here under “Options”, and can be set to 10, 15, or 30 total bands.
