Struct VolumeNode 

pub struct VolumeNode {
    pub volume: Volume,
    pub smooth_seconds: f32,
    pub min_gain: f32,
}

A node that changes the volume of a signal

Fields

volume: Volume

The volume to apply to the signal

smooth_seconds: f32

The time in seconds of the internal smoothing filter.

By default this is set to 0.015 (15ms).

min_gain: f32

If the resutling gain (in raw amplitude, not decibels) is less than or equal to this value, then the gain will be clamped to 0.0 (silence).

By default this is set to 0.00001 (-100 decibels).

Implementations

impl VolumeNode

pub const fn from_linear(linear: f32) -> Self

Construct a volume node from the given volume in a linear scale, where 0.0 is silence and 1.0 is unity gain.

These units are suitable for volume sliders (simply convert percent volume to linear volume by diving the percent volume by 100).

Construct a volume node from the given volume in percentage, where 0.0 is silence and 100.0 is unity gain.

These units are suitable for volume sliders.

pub const fn from_decibels(decibels: f32) -> Self

Construct a volume node from the given volume in decibels, where 0.0 is unity gain and f32::NEG_INFINITY is silence.

pub const fn set_linear(&mut self, linear: f32)

Set the given volume in a linear scale, where 0.0 is silence and 1.0 is unity gain.

These units are suitable for volume sliders (simply convert percent volume to linear volume by diving the percent volume by 100).

pub const fn set_percent(&mut self, percent: f32)

Set the given volume in percentage, where 0.0 is silence and 100.0 is unity gain.

These units are suitable for volume sliders.

pub const fn set_decibels(&mut self, decibels: f32)
