    2727    * JOSM (actually, Java's built-in audio facilities) doesn't recognise every variety of WAV file encodings. If you need to (JOSM will tell you), convert your recording to a suitable format using e.g. [http://audacity.sourceforge.net/ Audacity]. 8,000 16-bit samples per second is a reasonable format.
    2828
    29  2. Open your GPX file. This will create (a) a GPX layer showing the track and (b) a Marker layer containing the waypoints.
     29 2. [wiki:Help/Action/Open Open] your GPX file. This will create (a) a GPX layer showing the track and (b) a Marker layer containing the waypoints.
    3030    * if you don't see Markers, it is possible your GPS represents these by giving names/numbers to particular points on the track rather than separate waypoints. You can make Markers from these explicitly using [wiki:Help/Action/MarkersFromNamedPoints Markers From Named Points] from the context menu of the GPX layer; and automatically by turning on the 'Create markers from named trackpoints' option in [wiki:Help/Preferences/Audio Audio Preferences].
    3131    * if you don't see your number or names with the Markers, check that [wiki:Help/Action/ShowHideTextIcons Show/Hide Text/Icons] on the context menu for the Marker Layer is not off.
     
    3434    * If you don't see your names or numbers along with he Audio Marker icons, check that the 'Label audio markers' option in [wiki:Help/Preferences/Audio Audio Preferences] is on.
    3535
    36  4. Start synchronizing your sound track to the GPS data by clicking the icon for the waypoint you made at the synchronization cue. This should start playing your sound track.
    37     * 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.
    38 
    39  5. When you hear your synchronization cue ("NOW!"), [wiki:Help/Action/PlayPause pause] the play back.
    40     * if you started the recorder <em>after</em> 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, if any, to do this, as that would synchronize to the wrong marker.
    41 
    42  6. Select [wiki:Help/Action/SynchronizeAudio Synchronize Audio] on the context menu for the Marker Layer.
     36 4. Synchronize your sound track to the GPS data:
     37    a. Play your sound track by clicking the icon for the waypoint you made at the synchronization cue.
     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. When you hear your synchronization cue ("NOW!"), [wiki:Help/Action/PlayPause pause] the play back.
     40       * if you started the recorder <em>after</em> 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, if any, to do this, as that would synchronize to the wrong marker.
     41    c. Select [wiki:Help/Action/SynchronizeAudio Synchronize Audio] on the context menu for the Marker Layer.
    4342    * 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 offer the audio you recorded when you made that marker.
    4443
    45  7. Play each Marker and create the streets and features you described at the locations indicated by the Marker, in the usual way.
     44 5. Play each Marker and create the streets and features you described at the locations indicated by the Marker, in the usual way.
    4645    * If you start finding gaps in play back before you hear what you expect, or audio starts part way into your comment:
    4746      a. you may not have [wiki:Help/HowTo/AudioMapping/Calibration calibrated] correctly
    4847      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].
    49       c. you may need to re-synchronize (as per 4ff above) on a later marker (perhaps you paused while making the recording). Re-synchronization only affects later markers, so earlier ones will not change.
     48      c. you may need to re-synchronize (as per 4 above) on a later marker (perhaps you paused while making the recording). Re-synchronization only affects later markers, so earlier ones will not change.
