I'm super pumped for this jam and I just remembered some recordings I made back in 2014 that might help others out. This is a collection of 14 electromagnetic recordings I've published under the Creative Commons Attribution 3.0 (CC BY 3.0) license. What that means is these sounds are free to use, modify, and even sell as part of a commercial product (minus sound libraries) as long as you credit me with the creation of the original sounds. How do you do that? Easy! Just put my Twitter handle (@alfredofreak) along with a link to the pack in whatever credits screen / page / file you have.
Anyway, here's the link. EM recordings are pretty nuts. Have fun! :D
