Enum gstreamer_audio::StreamVolumeFormat

[−] Show declaration

pub enum StreamVolumeFormat {
    Linear,
    Cubic,
    Db,
    // some variants omitted
}

[−] Expand description

Different representations of a stream volume. StreamVolume::convert_volume allows to convert between the different representations.

Formulas to convert from a linear to a cubic or dB volume are cbrt(val) and 20 * log10 (val).

Variants

Linear

Cubic

Db
