I do like the Photoshop “droplet” concept. This is code derived from Photoshop’s software that will perform a set of tasks on a photo without ever opening Photoshop, or even the photo, for that matter. So, let’s say you drag several files to a droplet type macro to perform the same tasks and save them as a copy, in a new folder, or as the same files
If what you need is audio processing, WaveLab can already do that with the “watch folder” feature.
