Having bought a Nokia N810, which makes it easy to add waymarks, I revisited using continuous sound tracks in JOSM this week, meaning I don't have to have wires draped across my handlebars, nor keep pressing the pause button. Ideally I'll use a bluetooth mic and record on the N810 in future, but the sound quality isn't good enough that way yet.

So, I've reimplemented the rudimentary audio support in JOSM to thread the audio player, supply the usual controls, synchronise with waypoints and allow for a sampled set of waypoints when you can't create them explicitly, and to have a play head which follows your track in JOSM in real time. It makes audio mapping much easier both while surveying and while entering data.
