Struct AudioTrack 

pub struct AudioTrack {
    clip: AudioClip,
    gain: f64,
    fade_in_secs: f64,
    fade_out_secs: f64,
    play_range: Option<Range<f64>>,
}

A sound’s content data: the clip plus how to play it.

Purely substance — clip trim and gain envelope. Everything time-positional (placement, window duration, enable, rate warps — including linear speed changes via with_duration) lives on the cell layer (Unplaced::at, with_duration, with_rate_func, with_enabled), exactly like a visual item’s data versus its AnimNode.

Fields

clip: AudioClip

gain: f64

fade_in_secs: f64

fade_out_secs: f64

play_range: Option<Range<f64>>

Implementations

impl AudioTrack

pub fn new(clip: AudioClip) -> AudioTrack

A track playing the whole clip at unit gain.

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

Set the track’s linear gain.

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

Fade in linearly over the first secs of the track.

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

Fade out linearly over the last secs of the track.

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

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.

The range is clamped to the clip: a start before the clip pulls to zero, an end past the clip’s duration truncates, and an empty or reversed span collapses to silence. Content-time zero always plays range.start seconds into the clip.

Trait Implementations
