Struct Sound 

pub struct Sound {
    track: AudioTrack,
}

An audio leaf: plays a clip’s span inside its placed window.

Authored with Sound::new plus the track shapers (with_gain, with_fade_in, …), then composed exactly like a visual animation:

seq![
    square.fade_in(),
    Sound::new(narration),          // plays while the next cells run
    square.write(),
]

Fields

track: AudioTrack

Implementations

impl Sound

pub fn new(clip: AudioClip) -> Sound

A sound playing the whole clip at unit gain.

pub fn from_track(track: AudioTrack) -> Sound

A sound from a shaped track (gain, fades, play range).

pub fn with_gain(self, gain: f64) -> Sound

Set the sound’s linear gain.

pub fn with_fade_in(self, secs: f64) -> Sound

Fade in linearly over the first secs of the sound.

pub fn with_fade_out(self, secs: f64) -> Sound

Fade out linearly over the last secs of the sound.

pub fn with_play_secs(self, range: Range<f64>) -> Sound

Play only the clip’s seconds within range — a content trim, unlike the cell layer’s with_duration, which resamples the sound to fit a new window length.

pub fn duration_secs(&self) -> f64

The sound’s natural window length: the clip’s play length.

Trait Implementations

impl IntoAnimNode for Sound

impl Unplaced for Sound

fn at(self, offset_sec: f64) -> At<Self>

Place this definition at an offset in its parent’s local time coordinates.
