With a simple tool I developed in C#, I extracted all the wav tracks contained in the BIK video files of a game using the binkconv.exe CLI tool from RAD Video Tools.
In total I have extracted 500 videos then I have 500 directories, each directory contains 4 tracks with this incremental filenaming:
Now I'm stuck with the procedure, because I need to fuse/mix the four wav files into a new unique wav file.
I could do this manually with applications as Audacity, but we are talking about +500 folders in which each one contains 4 wav files, its an insane manual job then I need to find a way to automate it.
I need to do this via commandline application. or with a .Net audio lib that can fuse Wave audio files.
Which free command-line audio editing software could fuse wave files into a new one?.
This is a list of Software that I have installed:
Please note that I'm only pointing that I have installed those apps, but I'm not sure if one of the mentioned apps could do this task via command-line.
I think SoX maybe could be the best approach to do this, but I don't know how to.
