 Audio Markers have an icon associated with them, which when clicked causes the audio to play from the time assigned to the Marker by the offset from the start of the track.

+Audio markers are arranged as follows, unless the corresponding option is turned off in the 'When importing audio, make markers from...' section in [wiki:Help/Preferences/Audio Audio Preferences]:
 
- 1. At the location of any explicit waypoints in the GPX file (unless 'Import audio uses explicit waypoints' is turned off in [wiki:Help/Preferences/Audio Audio Preferences]).
+ 1. At the location of any explicit waypoints in the GPX file which have useful time stamps.
 
- 2. If that produced no markers, then at the location of any trackpoints which have explicit names (or descriptions) in the GPX file (unless 'Create audio markers from named trackpoints' is turned off in [wiki:Help/Preferences/Audio Audio Preferences]).
+ 2. At the location of any explicit waypoints which don't have useful time stamps but which are near the track, so can have their timing information inferred from the time stamps of the track points.

+ 3. At the location of any trackpoints which have explicit names (or descriptions) in the GPX file.
     * whether this is useful depends on how your GPS receiver manages its waypoints or marks.
