Can audio file be replaced in a batch operation?

[KriTa]

For test purposes, I have generated TTS for a project. After the course has been accepted, I want to replace all the audio files with real voice files. Is there a quick way to to this?

For the fastest turnaround you need to have all the audio voiceover split up into separate clips, one per slide.

Use a naming convention that clearly shows which slide each clip belongs to (e.g. Clip_Slide_01, Clip_Slide_05, etc)

Then all you need to do is import the clips into the Library and then drag each one from the Library and drop it on its relevant slide in the filmstrip.  That will cause it to replace the previous TTS clip on that slide.

However, if you have a lot of objects on each slide synched with the audio, you'll still need to synch them all up again.  There's no way to automate that.

Thank you Rod.

I figured this much myself. 

What I am looking for is a batch operation that will replace all the sound files at the same time. I have worked in other authoring tools where this is standardised.

To be honest, I find the most time-consuming part of the entire process to be re-timing of the objects on slide to match the new voiceover.  The rest only takes me a few minutes.
