[OSM-talk] voice recorders

[80n]

I've been using the built-in voice tagging capability of my camera for this
purpose.  It works exceptionally well.

Most digital cameras have a method of recording a voice tag along with a
photograph - although its often an obscure and poorly documented feature.

I don't actually take photos of a specific object - just press the shutter
button to get a time stamp.  You can then load the photos into JOSM and
synchronise them with your tracklogs.  You can then play the associated
voice tag to tell you what happened at that point.

It works really well once you get over the fact that some people think that
you are a nutter because you're talking to your camera.
