Soooo.... this took much longer than I thought. I had this almost done a few days ago, then I loaded it into Audacity in my Virtual Machine to remove some noises. When I then exported it, I saw that literally every 30 seconds, about 5 seconds of audio were just missing. (Not really missing, but made quiet to a point that it was neigh impossible to hear!)
Then I had everything cleaned again and was ready to add soundeffects and music. Just as I was about half way through, my backup laptop froze. Had to reboot, killing my entire progress.
The next attempt was, once again, the fault of my virtual machine. After adding soundeffects, I exported the file. Result: File was corrupted.
It is seriously a good thing that I keep the original files before edits, otherwise I would have had to re-record the whole thing each time. I can tell you that I am happy that this part is FINALLY DONE!
Sincerely
