Struct AudioProperties 

pub struct AudioProperties {
    pub gain: Animated<f32>,
    pub pan: Animated<f32>,
    pub fade_in: MediaTime,
    pub fade_out: MediaTime,
    pub fade_shape: FadeShape,

}

Per-clip audio presentation controls.

Fields

gain: Animated<f32>

Animated linear amplitude constrained to 0..=MAX_GAIN.

pan: Animated<f32>

Animated stereo position from -1 (left) to 1 (right).

fade_in: MediaTime

Fade-in duration measured from the clip’s timeline start. Non-negative.

fade_out: MediaTime

Fade-out duration measured back from the clip’s timeline end. Non-negative.

fade_shape: FadeShape

Curve used by both fades.

muted: bool

Silences this clip without removing it.

effects: Vec<AudioEffect>

Ordered single-input effects applied before the track bus, at most MAX_CHAIN_EFFECTS.

preserve_pitch: bool

Keeps the clip’s pitch when its speed is not 1 by time-stretching instead of resampling. No effect at speed 1, on loops or on freezes.

stream: Option<u32>

The source’s audio stream the clip plays, counted from 0 over the file’s audio streams in container order. Absent plays the stream the host picks by default.

channels: Option<Vec<u32>>

The stream’s channels the clip plays, by index. One index plays that channel as a mono source; two play a stereo pair, left then right. Absent plays every channel, folded by speaker position. At most two distinct indices.
