Struct GainControl 

pub struct GainControl(/* private fields */);

Thread-safe control for a Gain filter

Implementations

impl GainControl

pub fn gain(&self) -> f32

Get the current amplification in decibels

pub fn set_gain(&mut self, db: f32)

Amplify the signal by db decibels

Perceptually linear. Negative values make the signal quieter.

Equivalent to self.set_amplitude_ratio(10.0f32.powf(db / 20.0)).

pub fn amplitude_ratio(&self) -> f32

Get the current amplitude scaling factor

pub fn set_amplitude_ratio(&mut self, factor: f32)

Scale the amplitude of the signal directly

This is nonlinear in terms of both perception and power. Most users should prefer set_gain. Unlike set_gain, this method allows a signal to be completely zeroed out if needed, or even have its phase inverted with a negative factor.
