Synchronise Audio to Finish on Last Slide Without Shortening Slideshow (PTE AV Studio Pro 11)

[tonyb]

I’m using the Pro version of PTE AV Studio 11 and I have a slideshow where the soundtrack is set to begin halfway through Slide 2. The soundtrack is shorter than the total duration of the slideshow, and I want the audio to finish exactly on the last slide.

I don’t want to shorten the slideshow to match the audio — instead, I’d like to stretch or synchronize the audio timing so it ends with the last slide, keeping all my current slide durations intact.

Ideally, I’d like to sync the soundtrack from Slide 3 onward, while preserving the custom timing of Slides 1 and 2. Is there a way to do this within the Pro version?

This program has a primitive audio editor. You can create a copy of the audio file, you can cut the file, or cut out a fragment at the fading points (minimum volume) of the sound and paste it into the main track also at the fading point with small steps to the main track, the program will automatically add a crossfade to the junctions.
This is a difficult and painstaking job. That's why I always edit audio in the professional Adobe Audition program. It has a wonderful Remix feature, 
which allows you to lengthen and shorten the music to the desired length with an accuracy of up to a few seconds, which can be compensated by the length of the opening or ending credits.

I concur with Bad Dancer.

Do all the remaining slides have the same duration?

If so I would click on all the slides you want changed and adjust the timing slightly or just select some slides?

I generally work backwards and choose the slides and make the show, then select music (generally from the YouTube Free Audio Library) to fit the duration. I will fade the music out if it is longer which can easily be done.

Audacity is a good free audio editor but it does have a learning curve.
