public class RedNoise
extends UnitOscillator

RedNoise unit. This unit interpolates straight line segments between pseudo-random numbers to produce "red" noise. It is a grittier alternative to the white generator WhiteNoise. It is also useful as a slowly changing random control generator for natural sounds. Frequency port controls the number of times per second that a new random number is chosen.
