[][src]Enum gstreamer_audio::StreamVolumeFormat

#[non_exhaustive]pub enum StreamVolumeFormat {
    Linear,
    Cubic,
    Db,
    // some variants omitted
}

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 (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Linear

Linear scale factor, 1.0 = 100%

Cubic

Cubic volume scale

Db

Logarithmic volume scale (dB, amplitude not power)
