Enum SignalSource 

pub enum SignalSource {
    Energy,
    Beat,
    Bass,
    Highs,
    Stem(StemKind),
    Oscillator {
        frequency: f32,
    },
    Constant(f32),
}

A runtime signal in 0..=1.

Variants

Energy

The soundtrack’s loudness envelope (SoundtrackDef::energy).

Beat

1 on each beat, decaying linearly to 0 at the next (SoundtrackDef::beat_at).

Bass

Low band level. Live audio when playing; else the bass stem, else energy.

Highs

High band level. Live audio when playing; else the other stem, else energy.

Stem(StemKind)

A separated stem’s envelope; falls back to energy when the soundtrack carries no stems.

Oscillator

A free-running sine, 0..=1, at frequency Hz. Needs no soundtrack.

Fields

frequency: f32

Cycles per second.

Constant(f32)

A fixed value — for authoring and previews.

Implementations

impl SignalSource

pub fn needs_soundtrack(&self) -> bool

Signals that exist without a soundtrack.

pub fn free_running_at(&self, t: f32) -> Option<f32>

The value of a soundtrack-free signal at time t (seconds); None for signals a soundtrack provides.
