Virgil,
           I will possibly be classed as an heretic and ready to be 
broken on the wheel for
writing this on an LO user list, but IHMO there are much better ways of 
assembling a
slide presentation than using Libre Office.

These days, I use one of the video editors, e.g.  OpenShot, to make a 
synchronised slide
program.  The audio is recorded as a continuous sound track, then the 
images are dropped
in over the sound,  Perhaps it is a voice-under?

However, to answer your query, here is how I worked with LO, and it is 
streets ahead of our methods
used 40 years ago, where the audio editor was a razor blade plus a roll 
of quarter inch adhesive
tape.  Then, the images were 35mm slides, text slides were drawn, then  
photographed, and we
prayed that the processing laboratory would not change fluids while 
developing our film, thus
introducing colour shifts. On one job they did lose 2 36 shot-films from 
a 30+ batch, ruining a
week's work for 2 of our team who were making a training tape/slide 
program about measuring
water quality in remote lakes and rivers!

Libre Office.  The basic system allows the recording of sound for each 
slide, so I did this.


1. Sketch out a story and the sequence of images. Note that the images 
need to be ready in
   advance and that those with text or stepped bullets should be made 
and saved as separate files.

2. Draft a series of descriptions for each image. Record these as audio, 
with a good space
    between each one.

3. Edit the audio track - I used Audacity here - remove any pauses 
and/or hesitations and finish with
    a well spaced track.  This is then recorded as a sequence of 
separate audio files, one for each
    slide. While doing this, note the time/length of audio for each 
slide. Audio should be recorded
    in .wav format.  Best to leave a short silent period at the the 
beginning of each file so that viewers
    may look at a slide for a few seconds before the audio sarts

4. Now put the sequence together, assemble the slides with display times 
longer than the timed
    audio sequences. Then embed the relevant audio file for each 
slide.  Probably the start and
    finish visual slides will not have audio.

5.  Finally, run the whole program and perhaps adjust the transition 
times for each slide. I usually
     made the times a bit longer than needed, then pruned them at the end.

Awfully slow and only worth the effort, if the result is to be of 
benefit to many.

Gordon.
