The Visible Spectrum

This Wordpress plugin will count the visible characters in your post (including the spaces). After you unzip it, upload the plugin to your plugins directory and activate it. When you wish to count a character, just hit Count Characters, that’s all there is to it.

The power spectrum measures how much information is contained at each spatial frequency.Construction of the power spectrum takes three steps:1) Get the 2D (fftshifted) power spectrum2) Sample lines through sf=0 and rotated by 1degree intervals3) Average sampled lines to get resultThis function...

Acquires buffers of data from the system default sound card, calculates the power spectrum of the data and plots this along with the raw sampled data to screen.Useful as a quick and dirty (and completely uncalibrated) audio frequency spectrum analyser.Extends previous function...

Wavelength creates Color objects given the wavelength or the frequency of the light rather than the usual RGB or HSB. instead of: Color c = new Color(255, 0, 0); use the frequency in nanometers, and gamma 0.0. .. 1.0. (gamma is intensity/brightness.) Color c = Wavelength.wvColor( 400.0f, 0.80f );...
