On this settings page you can choose among various colormaps to represent the
\n intensities on the spectrum and spectrogram. You can also modify existing
\n colormaps or create your own.<\/p>\n

\n

\n

\n<\/a>Control Point Editor<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

The colored field on the left shows which colors represent a given
\n intensity level. Colors are interpolated between the existing control
\n points. You can move and change the control points with the mouse, or
\n create new control points by double-clicking into empty space:<\/p>\n

\n set to the background color of the Analyzer View.<\/p>\n

\n

\n
\n

\n<\/a>Space evenly<\/h4>\n<\/div>\n<\/div>\n<\/div>\n

This button will arrange all control points such that they all have the
\n same distance to each other. This can be used after you have changed the
\n number of control points and want them to be evenly spread.<\/p>\n<\/div>\n

\n
\n
\n
\n

\n<\/a>Interpolate colors<\/h4>\n<\/div>\n<\/div>\n<\/div>\n

If this is checked, the colors between the control points will be
\n smoothly interpolated. If the box is not checked, the color scheme will
\n use hard color boundaries between the different control points (also look
\n at the different but related setting Smooth Spectrogram
\n Colors).<\/p>\n

Here is an example of a spectrum with and without colormap interpolation:<\/p>\n

\n
\n
\n

\n<\/a>Reverse order<\/h4>\n<\/div>\n<\/div>\n<\/div>\n

Clicking this button will reverse the order of the control points, so that the colors for the highest intensity are now at the bottom, and vice versa. This will invert the appearance of the spectrogram and can be useful when trying out new color schemes.<\/p>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

\n<\/a>Displayed Dynamic Range<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

This is the range of intensities represented by the colormap. The
\n intensities are measured in decibels (dB). A value of 0dB corresponds to
\n the loudest possible sine wave that can be represented by the selected
\n audio format. With a recording bit depth of 16 bits per sample, it is
\n theoretically possible to represent a dynamic range of 96dB. However, on
\n the spectrogram it is often better to limit the shown dynamic range to
\n reduce the amount of displayed noise. The dynamic range sliders can also
\n be found on the toolbar and are useful for adjusting the displayed
\n dynamic range on the fly to get the best contrast on the
\n spectrogram.
\n The best way to understand those sliders is to play with both of them.<\/p>\n

\n
\n
\n
\n

\n<\/a>Dynamic Range Top Level (Brightness)<\/h4>\n<\/div>\n<\/div>\n<\/div>\n

This slider adjusts the top level (or saturation value) of the displayed
\n dynamic range. In the displayed spectrogram or spectrum, all values with
\n an intensity above the value of this slider will be displayed as maximum
\n intensity.<\/p>\n<\/div>\n

\n
\n
\n
\n

\n<\/a>Displayed Dynamic Range (Contrast)<\/h4>\n<\/div>\n<\/div>\n<\/div>\n

This determines the width or spread of the displayed dynamic range. A
\n large value will show more detail at the expense of clarity, and a small
\n value will make the stronger intensity values stand out more.<\/p>\n<\/div>\n

\n
\n
\n
\n

\n<\/a>Use current peak<\/h4>\n<\/div>\n<\/div>\n<\/div>\n

If this option is enabled, the colormap top will be set to the loudest
\n sample of the currently loaded audio file. Disable this option to set the
\n top value manually.<\/p>\n<\/div>\n<\/div>\n

\n
\n
\n
\n

\n<\/a>Linked UI Colors<\/h3>\n<\/div>\n<\/div>\n<\/div>\n

This tab will bring up a window similar to the Fonts and Colors editor. However, all changes
\n made here are local to the current colormap. For example, the background
\n color of the spektrum is normally determined by the global color scheme.
\n With the ‘Linked UI Colors’ feature, you can change the background
\n locally, for example to white. Similarly, you can adjust other UI element
\n colors to match your preferred colormap.<\/p>\n<\/div>\n<\/div>\n
