-With this method, you collect explicit waypoints along your track using the buttons on your GPS and at the same time dictate onto a continuous sound recording on your voice recorder what the waymark represents on the ground - a street name or point of interest. Your GPS notes three key pieces of information about each waypoint - its location, the time it was made, and it's name or number. The audio and waypoint data are then synchronized in JOSM so that you can play back each description by clicking on a Marker representing the waypoint.

 Each Marker is used to identify the position accurately and the voice recording is only used for annotation. Synchronization merely helps you to conveniently select the right part of the sound track to play for each marker.

-With this method you also make a continuous sound recording but instead of entering waypoints into your GPS you dictate an audible cue for each point of interest, for example "MARK! River Lane Primary School on left". Though there isn't a precise "location" for street names it will help to be consistent about recording the name just after you enter a street so you know where to look for the relevant clip.

 Synchronization of the sound track with the GPS data and calibration of the voice recorder's clock are then more critical because the time into the recording is used to accurately measure the equivalent time into the GPS track, and therefore the location.

 == [wiki:Help/AudioMapping/SeparateClips 3. Audio clips with waymarks] ==
 
-With this method, you make waypoints to identify locations of interest. However you record a separate audio file for each one and the name of each file is added as a <link> element in the corresponding waypoint in the GPX file before loading into JOSM. When JOSM then creates the Audio Marker for each waypoint, it knows which audio clip to play when you click on the marker.

 Advantages: by far the simplest method to work with in JOSM; no synchronization or calibration is required; ideal if you have an easy to use GPS that has a voice note function, or if you can automate linking the individual files to waypoint elements in your GPX file.
