Expand description

Audio-side transition event.

Variants§

Started

A proposal became current at a block boundary.

Fields

§previous_latency: usize

Latency of the engine being faded out.

§latency: usize

Latency of the new current engine.

§fade_frames: usize

Configured fade frames (0 for a cut).

Completed

The fade into this sequence completed; the old engine was handed back.

Refused

The proposal was refused mid-fade.

Superseded

The waiting proposal was superseded.

PrimingStarted

Priming of this proposal began under PrimingPolicy::History (Started follows when its fade starts, possibly at the same boundary).

Fields

§history_frames: usize

Recorded history frames the incoming engine will process.

AlignmentRefused

The proposal was refused at its start boundary because its latency differs from the current engine’s by more than the AlignmentPolicy::DelayLower maximum.

Fields

§previous_latency: usize

Latency of the current engine.

§latency: usize

Latency of the refused engine.

OutputLatencyChanged

The aligned output latency changed at this frame (only under AlignmentPolicy::DelayLower).

Fields

§previous_latency: usize

Output latency before the change.

§latency: usize

Output latency from this frame.
