How do I turn a discrete sound effect into a seamless loop?

Was there something wrong with my paulstretched solution? Is 10-11 seconds still not long enough?

I’m hesitant to try learning additional programs right now since I’m already a bit overwhelmed with learning every other aspect of game dev. I might try out Reaper like, a year from now when I’ve got a better grasp on my current tools.

And my current setup is not conducive to audio recording :c
