On this dialog you can choose among various colormaps to represent the intensities on the spectrum and spectrogram. You can also modify existing colormaps or create your own.
Colormap range
This is the range of intensities represented by the colormap. The intensities are measured in decibels (dB). A value of 0dB corresponds to the loudest possible sine wave that can be represented by the selected audio format. With a recording bit depth of 16 bits, it is theoretically possible to represent a dynamic range of 96dB. However, on the spectrogram it is often better to limit the shown dynamic range to reduce the amount of displayed noise. The colormap range slider can also be found on the toolbar and is useful for adjusting the displayed dynamic range on the fly to get the best contrast on the spectrogram.
Use current peak
If this option is enabled, the colormap top will be set to the loudest sample of the currently loaded audio file. Disable this option to set the top value manually.
Control Point Editor
The colored field on the left shows which colors represent a given intensity level. Colors are interpolated between the existing control points. You can move and change the control points with the mouse:
| Mouse action | Command |
|---|---|
| Click-Drag control point | Move control point |
| Shift + Click-Drag control point |
Move control point with more precision |
| Double-click control point |
Set color |
| Right-click control point |
Bring up context menu to set color or delete point |
| Double click empty space |
Create new control point |
Note: The lowest control point will always be set to the background color of the analyzer view.
