Enum kira::PlaybackRate

pub enum PlaybackRate {
    Factor(f64),
    Semitones(f64),
}

How quickly a sound is played.

Variants

Factor(f64)

The sound is played at a speed factor of the original playback rate.

For example, PlaybackRate::Factor(2.0) means the sound is played twice as fast as normal.

Semitones(f64)

The sound is played faster or slower so that the pitch of the sound is adjusted by the given number of semitones.

Implementations

impl PlaybackRate

pub fn as_factor(&self) -> f64

Returns the playback rate as a factor of the original playback rate.

pub fn as_semitones(&self) -> f64

Returns the number of semitones of pitch difference this playback rate will cause.

Trait Implementations

impl Clone for PlaybackRate

fn clone(&self) -> PlaybackRate

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PlaybackRate

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<f64> for PlaybackRate

fn from(factor: f64) -> Self

Converts to this type from the input type.

impl PartialEq<PlaybackRate> for PlaybackRate

fn eq(&self, other: &PlaybackRate) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Tweenable for PlaybackRate

fn lerp(a: Self, b: Self, amount: f64) -> Self

Returns an linearly interpolated value between a and b.

impl Copy for PlaybackRate
