Detailed Description

template<class RNG = RNGLinCon>
class gam::NoiseBrown< RNG >

Brownian noise.

Brownian noise has a power spectrum of 1/f^2. It is produced by integrating white (uniform) noise. The output value is clipped within a specified interval.

Constructor & Destructor Documentation

NoiseBrown	(	float	val = 0,
		float	step = 0.04,
		float	min = -1,
		float	max = 1,
		uint32_t	seed = 0
	)

Parameters:

[in]	val	start value
[in]	step	accumulation step factor
[in]	min	minimum of clipping interval
[in]	max	maximum of clipping interval
[in]	seed	random number generator seed; 0 generates a random seed
