I briefly forgot what world I was in and assumed "standalone" meant there'd be wav files. lol. Nope. it's just a standalone app with no wav files to be found.
It would seem the samples are stored in their own special format, which lucky for me just seems to be a giant JSON file. Yup, the samples are stored in there as an array with text-based floating point representation. It's a terrible design, but hey at least they made it trivial to parse. Extracting these will be a future project. Hopefully I'll be able to salvage my purchase.
