Prerequisites:

Read the tutorial on syncing a slider to a data-source.

The project file created for this tutorial can be downloaded here.

Step 1: Click the ♺ to start analyzing audio inputs. Adjust the gain slider if your levels are too high or too low.

If needed change the audio interface from the devices menu.

Tip: Some audio interfaces, including the built-in microphone, have their own gain sensitivity level control that can be set in the System Preferences under Sound, or on the physical device itself.

Step 2: Click and drag on filters to change their frequency center and range.

Drag left and right to change center frequency.
Drag up and down to change the width of the filter.
Use the inspector to add, remove, rename and customize the settings for individual filters.
