Sound Events

Resources → Audio contains imported MP3/WAV/OGG sound effects. Drag an audio file onto any frame of the Timeline ruler to create a small speaker marker, or choose Add at Playhead. Use Play beside an imported file to audition it; starting another preview stops the previous one. Playback crossing the marker plays the sound once. Drag the marker horizontally to retime it; select it to edit the audio file, exact frame, volume, start offset and retrigger behavior. Multiple sounds may share one frame and appear as stacked markers. Sound Events create neither canvas layers nor audio tracks. A sound fires when playback enters its marker frame; leaving that Step with Take Out does not replay it. Starting a new IN after OUT arms the Sound Events again.

For action-triggered audio, expand the imported file and choose Create Playback Cue instead of Add at Playhead. The cue appears under Resources → Media with a Manual trigger. Expand it, change Trigger type to Custom Action, and select the action ID. Preview & Export exposes a button for each Custom Action so the audio can be tested directly.
