    2929    * 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. You will need to apply the timestamps of the old files onto the new ones if you have to do this; the Unix command ''touch'' can do this easily if you use consistent naming. On Windows, you can get ''touch'' as part of [http://www.cygwin.com/ cygwin].

Select all the relevant WAV files (CTRL and SHIFT click to add and remove files in the selection). This should a produce Marker Layer containing one audio marker for each file labelled with the file name (excluding the ".wav").
    36     * if you don't see labels with the Markers, check that [wiki:/Help/Action/ShowHideTextIcons Show/Hide Text/Icons] on the context menu for the Marker Layer is not off.

    38  4. Make the map using your commentary. Click on the markers to play the corresponding audio. You can move the play head within any one recording's range and use the [wiki:Help/Action/AudioFwd jump forward], [wiki:/Help/Action/AudioFaster fast forward] and [wiki:/Help/Action/AudioSlower slow forward] audio controls, but you can't drag the play head to positions between recordings.

    40       a. you may not have [wiki:/Help/AudioMapping/Calibration calibrated] correctly
    41       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].
