[OSM-talk] More JOSM audio

[David Earl]

Following helpful comments from Chris Morley and others, I've done some 
more work on the JOSM audio interface, which makes the non-waypoint 
method with continuous sound tracks easier to use. These should be in 
tomorrow's build.

It's all written down in the JOSM help, at
   http://josm.openstreetmap.de/wiki/Help/HowTo/AudioMapping
but here is a brief summary of the changes:

1. You can now drag the orange play head marker around to jump the audio 
to the nearest trackpoint to the mouse-up position. (Take care with the 
nearest track point if you went both ways down a road).

2. You can synchronize the audio by playing to the cue first, then 
choosing the geographical location by SHIFT+Dragging the play head (the 
previous method, which operates the other way round, is still there). 
The target location can either be a trackpoint or an audio marker (so it 
works for both audio mapping with explicit waypoints or just an audio 
commentary).

3. _Both_ methods now start from "Import Audio" on the GPX layer context 
menu. If you aren't using explicit waypoints, this now gives you only 
one audio marker, at the start (so the plethora of markers from sampling 
has gone - you don't need them now you can drag the play head to jump 
the audio; waypoint users may want to turn off the automatic creation of 
plain waypoint markers using the option provided in Audio Preferences).

(As well as making both methods more similar, it also makes it more 
similar to Import Images. If you have explicit waypoints, there is now 
also an option to turn off automatic creation of simple markers. If we 
were ever able to recognize a "voice marker" in the sound track, this 
also provides an obvious place to put it).
