Hi,

I'm recording lectures (persentations with voice) for replay later, in
a live environment i.e. once off with no post editing possibilities.

It works fine using the record narration function if a presenter only
goes forward from one slide to the next.  The trouble starts when a
presenter flips between slides e.g. goes back a slide and then forward
i.e. from slide 3 to 2 and then back to 3.  In this instance, the
original audio files for the slides e.g. (2) are overwritten.

Is there a way to have separate audio files per action, so that back
and forward movements are recorded (in separate files) and are
synchronised correctly?

If not, is there an alternative way/software?

Cheers,
Antoine.
