Processing : Elastic Audio : Editing in Warp View : Event Markers

Event Markers
Event markers indicate detected (or manually created) audio events. Event markers are only displayed in Warp view and Analysis view. In Warp view, Event markers appear as gray vertical lines that do not fully extend to the top and bottom of the track. With the Grabber tool in Warp view, you can drag Event markers to apply various kinds of warping depending on whether or not Warp markers are present in the clip as well. In Warp view, you cannot add, relocate, or delete Event markers. Use Analysis view to edit Event markers (see Editing in Analysis View).

The display of Event markers is dependent on Horizontal Zoom. If you are zoomed out too far, Event markers are not displayed. To see Event markers, zoom in.
