Random Noise by Color (chart) and signal production

Random Noise by Color (Various Noise Distributions)

Sometimes it is desirable to mask background audio using random noise. Your Diamond Cut Make Waves Generator (found under the Edit menu/Make Waves) provides you with various distributions of noise that you can produce. Random noise can be used to mask conversations or to simply create a background environment more conducive to sleep or relaxation. Check them out and hear what they sound like.

Color (or type)	Characteristics	Slope	Density
White	Equal Energy per unit Hertz	Flat	Uniform
Pink	Equal Energy per unit Octave	-3 dB/Octave	1/F
Brown	Analogous to Brownian Motion	-6 dB/Octave	1/F^2
Red	Another name for Brown Noise	-6 dB/Octave	1/F^2
Blue	Azure Noise (proportional to F)	+3 dB/Octave	F
Green	Pink Noise with Emphasis at 500 Hz	Non-Linear	Somewhat Subjective
Violet	Differentiated White Noise	+6 dB/Octave	F^2
Grey	Psychoacoustic equal loudness Curves	Proportional to SPL	Varies with loudness
Seismic	Random Noise below 20 Hz	-3 dB/Octave	In-audible
Black	Analogous to black body radiation	Silence	Edit/Mute

These various Random Noise distributions (by color or mathematical distribution) can be created directly via the Make Waves Generator. They can also be found as a series of White to X Color Multifilter Presets portion of the software program.

I guess that this new set of features could be called either Hi-Fi to Dine By or The Relaxer". It could also be called "The Sound Masker".
