Parametric EQ | Virtual View - AVX Architect
This video covers the Parametric EQ object in the Virtual View of AVX Architect, part of a series on audio processing objects. You’ll learn Parametric 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 Parametric EQ object.
The Parametric EQ is found in the virtual view, under the “Equalization” section of the audio processing objects. The Parametric EQ allows you to boost or cut specifically desired frequency bands. In the Parametric EQ window, we’ll first notice the frequency graph that shows all of our bands and the changes they’re making. In this example, we’ve got a 5-band EQ.
Below the frequency graph, we can see each bands’ parameters. Starting at the left, we have “Type”, which can set the filter to be a low shelf, bell, or a high shelf. With our low and high shelf filters, the “Slope” option is available to select how steep the slope is at the cutoff frequency. Next, under “Frequency” and “Boost/Cut” we can set the desired frequency for our filters and their gain setting by typing directly into the text boxes or using the bump up and down buttons. Bell curve filters have an adjustable “Width”, or Q, setting to make the filter wider or narrower, perfect for taming troublesome feedback. Lastly, the “Enable” buttons are available on every filter band to independently bypass or disable specific filters. The frequency spectrum graph can also be interacted with directly. The band indicator numbers can be dragged to change just the frequency. The main circle indicators can be moved to adjust both frequency and gain. To the side of the main circle indicators, you can drag these transparent circles to adjust the width parameter.
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” shows 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 in directly or by using the bump up/down buttons. 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 a minimum of 1 and a maximum of 24 total bands.
