Hello! 

This is the readme file for the CirSpectrum Vis Plugin.  

CirSpectrum produces a circular spectrum with peak and inertia features.  

You have many options:

First the four options determining the look of the CirSpectrum:

circular, vertical, symmetric and excentric. 

Each of these option may take a boolean value {0,1}.
The circular option makes the spectrum circular (1) or linear (0).
The vertical option makes the spectrum drawn on a vertical (1) or horizontal (0) line.
The symmetric option changes the color filling (1 is mirror symmetry, 0 is central symmetry).
The excentric option draws basses in the centrum (1) or at both ends (0). 
If you choose another positive value X for one or several of these four options, 
then CirSpectrum makes animated transitions between both states, at a frequency 
specified by X (to have a nice result, choose values greater than 128)

Now you have the options regarding the body of the spectrum:

spectrum_visible={0,1} hides the spectrum when 0 (default is 1)
spectrum_smoothness={0,...,64} allows to smooth peaks and falls in the spectrum
lsp_main_color={8 digits hex} is the color of the left  spectrum body
rsp_main_color={8 digits hex} is the color of the right spectrum body
lsp_peak_color={8 digits hex} is the color of the left  spectrum peak
rsp_peak_color={8 digits hex} is the color of the right spectrum peak

... and the options for the inertia feature:

inertium_visible={0,1} hides inertia when 0 (default is 1)
inertium_strength={1,...} slows down the fall of inertia
lin_main_color={8 digits hex} is the color of the left  inertia body
rin_main_color={8 digits hex} is the color of the right inertia body
lin_peak_color={8 digits hex} is the color of the left  inertia peak
rin_peak_color={8 digits hex} is the color of the right inertia peak

The inertia feature looks pretty well when you choose colors that are 
the half or the third of the spectrum colors.  

Note that the procedure for drawing circles don't use any (co)sine, nor any 
multiplication, but only integer additions and substractions!!!

Enjoy!
