Synthesizer.State.NoiseCustom

Description

Noise and random processes. This uses a fast reimplementation of randomR since the standard function seems not to be inlined (at least in GHC-6.8.2).

Synopsis

white :: (C y, Random y) => T y
whiteGen :: (C y, Random y, RandomGen g) => g -> T y
whiteQuadraticBSplineGen :: (C y, Random y, RandomGen g) => g -> T y
randomPeeks :: (C y, Random y) => T y -> T Bool
randomPeeksGen :: (C y, Random y, RandomGen g) => g -> T y -> T Bool
randomRs :: (C y, Random y, RandomGen g) => (y, y) -> g -> T y
randomR :: (RandomGen g, C y) => (y, y) -> g -> (y, g)

Documentation

white :: (C y, Random y) => T y Source #

Deterministic white noise, uniformly distributed between -1 and 1. That is, variance is 1/3.

whiteGen :: (C y, Random y, RandomGen g) => g -> T y Source #

whiteQuadraticBSplineGen :: (C y, Random y, RandomGen g) => g -> T y Source #

Approximates normal distribution with variance 1 by a quadratic B-spline distribution.

randomPeeks Source #

Arguments

:: (C y, Random y)
=> T y	momentary densities, `p` means that there is about one peak in the time range of `1/p` samples
-> T Bool	Every occurence of `True` represents a peak.

randomPeeksGen :: (C y, Random y, RandomGen g) => g -> T y -> T Bool Source #

randomRs :: (C y, Random y, RandomGen g) => (y, y) -> g -> T y Source #

randomR :: (RandomGen g, C y) => (y, y) -> g -> (y, g) Source #
