Marker Audio

Use Audio to add sound behavior to a selected marker.

The Type dropdown chooses the audio mode. In the screenshot it is set to None, which means the marker has no audio behavior configured.

Once an audio type is selected, extra fields appear for source and playback. Set Type to None for silent markers when label or action already provides context.

Steps: Expand markers section → Select the first marker in the list to open the properties panel → Open the Audio section → Expand all collapsed fieldsets in the Audio section
