Translations:+4D Soundanleitung/3/en

According to forum posts, the +4DSound program is languishing in obscurity, even though many users are surely interested. I suspect that for many model railroaders, getting started with this program is very time-consuming, and most give up after a few hours due to a lack of success. After all, apart from a minimal example, there isn't a single fully prepared locomotive with the corresponding sound files.
