    v4 v5  
    3434    * if the markers are too dense or too far apart, you can vary the sampling rate using the two 'Min audio marker sample rate' options [wiki:Help/Preferences/Audio Audio Preferences]. By default they are at least 75 metres and 15 seconds apart.

     36 4. Locate your synchronization point near the beginning of the track. Unless you are very lucky, there won't be a Marker exactly at that point, so you need to add one:
     37    a. Play the audio by clicking on the marker immediately before the synchronization point, ignoring what it is saying. When the orange play head arrow reaches the synchronization location, [wiki:Help/Action/PlayPause pause the Audio].
     38       * if you don't see an orange play head arrow moving along the track while you play audio, make sure the 'Display live audio trace' option in [wiki:Help/Preferences/Audio Audio Preferences] is on.
     39    b. [wiki:Help/Action/MakeAudioMarkerAtPlayHead Make Audio Marker At Play Head] using the context menu (right mouse button) of the Marker Layer to add the extra point.

    38  5. Play the audio by clicking on the marker immediately before the synchronization point, ignoring what it is saying. When the orange play head arrow reaches the synchronization location, [wiki:Help/Action/PlayPause pause the Audio].
    39     * if you don't see an orange play head arrow moving along the track while you play audio, make sure the 'Display live audio trace' option in [wiki:Help/Preferences/Audio Audio Preferences] is on.
     41 5. Synchronize your sound track to the GPS data:
     42    a. Play the audio from the synchronization point by clicking the icon you just added.
     43    b. When you hear your synchronization cue ("NOW!"), [wiki:Help/Action/PlayPause pause] the play back.
     44       * if you started the recorder after getting a GPS fix, you will need to [wiki:Help/Action/Back jump backwards] in the sound track. Don't click on an earlier marker to do this, as that would synchronize to the wrong marker.
     45    c. Select [wiki:Help/Action/SynchronizeAudio Synchronize Audio] on the context menu for the Marker Layer.
     46       * The play head should jump back to the marker, and when you play the marker you should hear your "NOW!" cue. Clicking on other markers should play the audio for that point along the track.
    4047
    41  6. [wiki:Help/Action/MakeAudioMarkerAtPlayHead Make Audio Marker At Play Head] using the context menu (right mouse button) of the Marker Layer to add the extra point.
    42 
    43  7. Start synchronizing your sound track to the GPS data by playing the audio from the synchronization point by clicking the icon you just added.
    44 
    45  8. When you hear your synchronization cue ("NOW!"), [wiki:Help/Action/PlayPause pause] the play back.
    46     * if you started the recorder after getting a GPS fix, you will need to [wiki:Help/Action/Back jump backwards] in the sound track. Don't click on an earlier marker to do this, as that would synchronize to the wrong marker.
    47 
    48  9. Select [wiki:Help/Action/SynchronizeAudio Synchronize Audio] on the context menu for the Marker Layer.
    49     * The play head should jump back to the marker, and when you play the marker you should hear your "NOW!" cue. Clicking on other markers should play the audio for that point along the track.

    51  10. You may find it convenient to use the automatically generated markers to jump in to your sound track, or instead to use the [wiki:Help/Action/Forward jump forward], [wiki:Help/Action/FastForward fast forward] and [wiki:Help/Action/SlowForward slow forward] audio controls to work your way through the sound track. Either way, when you hear your "MARK!" cues, pause the recording, and the play head will indicate the corresponding location and therefore where to add your feature to the map.
     48 6. Make the map using your commentary. You may find it convenient to use the automatically generated markers to jump in to your sound track, or instead to use the [wiki:Help/Action/Forward jump forward], [wiki:Help/Action/FastForward fast forward] and [wiki:Help/Action/SlowForward slow forward] audio controls to work your way through the sound track. Either way, when you hear your "MARK!" cues, pause the recording, and the play head will indicate the corresponding location and therefore where to add your feature to the map.
    5249    * If you aren't using the markers much, and they are in the way, you can turn them off (once you have synchronized) using [wiki:Help/Action/ShowHideTextIcons Show/Hide Text/Icons] on the context menu (right mouse button) on the Marker Layer; the play head will remain visible.
    5350    * If you start finding play back isn't happening where you expect:
    5451      a. you may not have [wiki:Help/HowTo/AudioMapping/Calibration calibrated] correctly
    5552      b. you may have been speaking too soon or too late while mapping: you can insert a lead-in time to compensate for this using 'Lead-in time' in [wiki:Help/Preferences/Audio Audio Preferences].
    56       c. you may need to re-synchronize (as per 7ff above) at a later point (perhaps you paused while making the recording). Re-synchronization only affects later markers, so earlier ones will not change.
     53      c. you may need to re-synchronize (as per 5ff above) at a later point (perhaps you paused while making the recording). Re-synchronization only affects later markers, so earlier ones will not change.
