Control Dialog

 

Active Band selects the current band to be adjusted.  Center Freq (Hz) controls the center frequency for the current band. Gain (dB) adjusts the amount of cut or boost applied at the center frequency for the current band.  Maximum Gain specifies the maximum possible setting of the Gain parameter for the current band.  Values between 0 and 15dB can be set.  Minimum Gain specifies the minimum possible setting of the Gain parameter for the current band.  Values between -30 and 0dB can be set.  Bandwidth (oct) controls the range of frequencies, above and below the center frequency, which are affected by the current band.  Values between 0.01 and 4 octaves in hundredths of an octave can be set.

The settings may also be adjusted by using Drag Points.  This allows the setting of frequency band controls shown inside the graph.  Dragging the larger center dot affects both Center Freq & Gain.  Dragging either smaller outer dot affects Bandwidth.  

Flatten Band and Flatten All change the gain of the current band or all bands to 0dB (flat).  Bypass Band and Bypass All disable the band(s) without changing settings.  Drag Points turns on/off the band controls, revealing the resultant curve only.  Band highlights the current band inside the graph.
