rng: Rng

Implementations

impl Noise

pub fn new(nid: &NodeId, _node_global: &NodeGlobalRef) -> Self

pub const atv: &'static str = "Attenuverter input, to attenuate or invert \ the noise"

pub const offs: &'static str = "Offset input, that is added to the output \ signal after attenuvertig it."

pub const mode: &'static str = "You can switch between **Bipolar** noise, which \ uses the full range from **-1** to **1**, or **Unipolar** noise that \ only uses the range from **0** to **1**."

pub const sig: &'static str = "The noise output."

pub const DESC: &'static str = r#"Noise Oscillator This is a very simple noise oscillator, which can be used for any kind of audio rate noise. And as a source for sample & hold like nodes to generate low frequency modulation. The white noise is uniformly distributed and not normal distributed (which could be a bit more natural in some contexts). See also the `XNoise` node for more noise alternatives. "#

pub const HELP: &'static str = r#"A Simple Noise Oscillator This is a very simple noise oscillator, which can be used for any kind of audio rate noise. And as a source for sample & hold like nodes to generate low frequency modulation. The noise follows a uniform distribution. That means all amplitudes are equally likely to occur. While it might sound similar, white noise is usually following a normal distribution, which makes some amplitudes more likely to occur than others. See also the `XNoise` node for more noise alternatives. The ~~atv~~ attenuverter and ~~offs~~ parameters control the value range of the noise, and the ~~mode~~ allows to switch the oscillator between unipolar and bipolar output. "#
