Noise (electronics) | Random number generation
A noise generator is a circuit that produces electrical noise (i.e., a random signal). Noise generators are used to test signals for measuring noise figure, frequency response, and other parameters. Noise generators are also used for generating random numbers. (Wikipedia).
What is Sound? - Quickly Discover What Sound Really Is
What is Sound? This simple demonstration visually shows how sound waves are produced from a vibrating surface. A frequency generator is hooked up to a power amplifier, and the resultant signal is used to drive a loudspeaker. The signal is also sent to an oscilloscope. After listen

Here's how electrostatic speakers work. Unless your an audiophile, you've probably never heard of the electrostatic loudspeaker. Electrostatic loudspeakers are pretty hip in the audiophile World because they exhibit levels of distortion one to two orders of magnitude lower than conventi

Programming Perlin-like Noise (C++)
NOTE! This is an approximation of Perlin Noise! :-S Noise is at the root of most procedurally generated content. However, just choosing random numbers alone is insufficient. Perlin noise adds local coherence over different scales to generate natural looking formations, which can be furthe
