Struct Decibels

pub struct Decibels(pub f32);

Expand description

Represents a change in volume.

Higher values increase the volume and lower values decrease it. Setting the volume of a sound to -60dB or lower makes it silent.

Tuple Fields§

§0: f32

Implementations§

impl Decibels

pub const SILENCE: Decibels

The minimum decibel value at which a sound is considered silent.

pub const IDENTITY: Decibels

The decibel value that produces no change in volume.

pub fn as_amplitude(self) -> f32

Converts decibels to amplitude, a linear volume measurement.

This returns a number from 0.0-1.0 that you can multiply a singal by to change its volume.
