To accomplish the endless loop, producing the same soundtrack over and over, should I just record the .wav soundtrack one after the other with no “gaps” in between to complete the “endless loop”?
What do you think?
At the risk of repeating myself, I am not sure what you are trying to do here. The .WAV spec by nature is of finite length.
If you import a .WAV file, do Ctrl+A (select), then Ctrl+D (duplicate) 4 times, you will have 16 copies of your original audio. If you then do Tracks > Align Tracks > Align End to End, you will have audio that plays 16 times longer than the orignal. File > Export should convert that file for you.
If you want to record audio continuously, 24/7, and start overwriting memory after, say, a week, then you’ll need different recording software, (Audacity was not designed for surveillance).
