Actively managing the recording process in the way you suggest makes it harder to record. Making it harder to record means you get less content. It also makes capturing many things very difficult.
Some situations where point recording doesn't work well:
- While driving. It is flat out dangerous to mess with a device. We all do it, with cell phones and the like, but that doesn't make it right.
- While on a bicycle, skiing, sailing, surfing, kite boarding, skateboarding, rock climbing, unicycling, pogo sticking, or any activity that requires our focus or the use of our hands for other things.
Then there are cases where the reason for the data
collection is tied to the movement. How fast were you going when
sound levels rose above 'n dB?' What were you saying, or what was
the ambient sound, when you went over 'y MPH?' But then, that
assumes we know in advance what we are going to do with the
recording.
Why do you want to require a sound recording, which is a record of air pressure over time to be divorced from the track, which is a record of location over time? What is the benefit of reducing the track log, a combination of location and time, to a single point?
The connection between audio and location is not that clear cut. The audio I record does not necessarily discuss the location where it was recorded. But that doesn't make the location irrelevant.
Everything that we do, think, or experience happens in a place, and at a time. (if one wanted to be snooty in an arty way you could say 'all human experience has a spatial and temporal context' ). The audio record that we create is one attribute or artifact (or sonic debris field) of our transit through time, and space. It is not the only one.
For example, on a trip in 2000 I did experiments on geocoding text. Not a text file, but the text within. My goal was to have each word (and then each letter) associated with a time and position. Absurd? Perhaps, but that is how I think....
Anyway, that is part of my thinking on the issue.
Like what? I can't imagine any circumstance in which a path would be
more useful than a point.

Perhaps, as Tom suggested, it would be
better for the audio to be continuous, with the point merely being
inserted out of band into the audio stream.

I agree with you that having an audio file and a movement track
correlated is better than not having the movement information. I
think it would be better to have begin/end markers that says "this
segment of audio discusses this location".
