Function dsp::signal::noise_simplex

pub fn noise_simplex<S>(phase: Phase<S>) -> NoiseSimplex<S>

Produces a 1-dimensional simplex noise Signal.

This is sometimes known as the "drunken walk" or "noise walk".

Example

extern crate sample;

use sample::signal;

fn main() {
    // Creates a simplex noise signal oscillating at 440hz sampled 44_100 times per second.
    let mut signal = signal::rate(44_100.0).const_hz(440.0).noise_simplex();
    for n in signal.take(1_000_000) {
        assert!(-1.0 <= n[0] && n[0] < 1.0);
    }
}
