MASQ's suggestion is likely the best bet.

100 files... well, if each file is short + has a few splits.

If files are long with many splits, scripting ffmpeg might be the way to go.

Also if you're adding files in the future, where you have to repeat this task, scripting ffmpeg will be way faster than a GUI based system.

https://stackoverflow.com/questions/36074224/how-to-split-video-or-audio-by-silent-parts turned up in a quick search.

This is a two step process.

1) 1st pass - find locations of silence gaps, based on some level/decibel threshold.

2) 2nd pass - split file based on locations found.

Pretty straight forward.

You could go one step more + normalize all audios to EUR128 broadcast levels, so your entire library matches level/loudness, which will be great if you're turning these recordings into a series of Podcast episodes.
