Converting hca files?

[Fat Scout]

I'm attempting to extract audio from the Danganrompa V3 demo, but I've hit a wall with trying to convert the hca files I got from converting the awb files I extracted from the cpk. I have tried using hca2wav, but it didn't work, and I don't really know much about hex editing and file headers, so I'm not entirely sure the headers used by the hca files. I've also got a few samples of some of the extracted files in case they are needed, just copypaste this link in your searchbar, and it should take you to the files. https://mega.nz/#F!dO4ykCRZ!NZzIuUfU-E2VqgcPEBTDKA
