Display and workflow

The large display shows all EQ bands and lets you easily create new bands and edit them. The thick yellow curve shows the overall frequency response of the equalizer. The EQ display looks simple and straightforward, but holds a lot of intelligence and smart features. We strongly recommend to take some time to read this topic and learn about all its options and short-cuts... it will highly improve your workflow!

Interactive EQ display

Creating bands

  • To add a new EQ band, simply click on the yellow overall curve and drag it up or down.
  • Alternatively, double-click or Ctrl-click (Command-click on Mac OS X) on the display background.

The shape of newly created curves is determined automatically depending on where you click, and once you get used to this, it's a real time-saver! Do you need a Notch curve? Just double-click in the far low area of the display. Want a Low Cut or High Cut filter? Double-click in the far left or far right areas. Shelving filter? Drag the yellow curve at the left or right of the display.

Selecting bands

  • Click the EQ band's dot or the colored area around it to select it.
  • Click and drag on the display background to select adjacent bands by dragging a rectangle around them.
  • Hold down Ctrl (Command on Mac OS X) and click another dot to select multiple bands. Hold down Shift and click a dot to select a consecutive range of bands.
  • Deselect all bands by clicking anywhere on on the display background.

Adjusting and editing bands

Once you have one or more EQ bands selected, the display highlights the shapes of the selected bands. You can now of course edit the EQ settings via the floating band controls, but the easiest way to adjust them is simply by dragging them around:

  • Click and drag a selected dot to adjust the frequency and gain of all selected bands. If you have multiple bands selected, the gain of all selected bands will be scaled relative to each other.
  • Use the mouse wheel to adjust the Q setting of the selected bands, making them narrower or wider. This works while dragging or when the mouse pointer is above a curve. Alternatively, hold down Ctrl (Command on Mac OS X) while dragging vertically to adjust the Q of all selected bands.
  • Hold down Shift while dragging to fine-tune the settings of the selected bands.
  • Hold down Alt while dragging to constrain to horizontal adjustments (frequency) or vertical adjustments (gain or Q, depending on the Ctrl/Command key).
  • Hold down Alt and click the dot on an EQ band once to toggle its bypass state (enabling or disabling the band).
  • Hold down Ctrl+Alt (Command+Alt on Mac OS X) and click the dot on an EQ band once to change its shape.
  • Hold down Alt+Shift and click the dot on an EQ band once to change its slope.
  • Double-click a dot to enter values in the parameter value display (using the Tab key to step through Frequency, Gain and Q) or double-click the values in the parameter value display directly. Note that you can enter frequencies in various ways, like "100", "2k", "A4" or "C#2+13".
  • If you right-click on the dot for an EQ band, a pop-up menu appears with various band settings. This is a quick way to modify the EQ band while you're working in the display.

Display range

Note that two display scales are drawn: the yellow scale corresponds to the EQ band curves and yellow overall curve. The gray scale at the far right is used by the spectrum analyzer and output level meter. In the top-right corner of the display at the top of the yellow scale, there is a drop-down button to choose the display range: +/- 3 dB, 6 dB, 12 dB or 30 dB. When you are dragging a curve outside the current range of the display, the range will expand automatically as needed.

Horizontal zooming

Sometimes it might be useful to zoom in to a specific frequency for extra precise editing. You can easily do this by clicking and dragging the frequency scale at the bottom of the EQ display, just above the bottom bar. You can do the following:

  • Click and drag up and down to zoom in and out at the frequency you have clicked on.
  • While zoomed in, you can also drag left and right to move the frequency scale.
  • Just double-click the scale to return to its default full range.


  • In Full Screen mode, available via the button at the right top of the interface, the EQ display will fill the whole screen so you can make very precise adjustements. See Full Screen mode and resizing.
  • To quantize a frequency without using the piano display, just double-click a curve dot in the display or the Frequency knob in the EQ controls, and enter a value like "A4" or "C#2".
  • It is possible to turn off the automatic adjustment of the display range by clicking Auto-Adjust Display Range in the Help menu.
  • Even though frequencies above 20 kHz are generally inaudible, the display extends to 30 kHz so you can put filters above this limit. The left part of the filter, extending into the audible frequency spectrum, still affects the sound. This gives you even more possibilities to shape the frequency response of the equalizer just the way you need it.
  • On iOS, the display behaves slightly differently. See Using on iOS.
