audio_effect¶
Per-Scene audio: timed sound effects and the narration source.
AudioManager is owned by each Scene – there is no
process-global audio state, so two Scenes in one process can use different voices
or recorded narration without interfering. It holds the Scene’s speech generator,
its accumulated transcript, and the list of effects to mix.
AudioEffect is one sound placed at one time on the Scene’s timeline.
The Audio and
Speech contexts add them,
taking their runtime from the clip so the animations inside are fitted to the
sound. save_video composes every effect into one track and hands it to the
video writer.
