this voice somehow fits for metal sonic

I don't know if you can help or not. I'm trying to get Mangio 23.7.0 running without paying a 3rd party site a rip-off subscription. Mangio is all set up on my 2017 iMac, but when I do the pre-processing of my audio file, it never ends, I let it run 24 hours and nothing. I can't even get to the second part. How long should a 5-10min crystal clear audio clip take? 5-10mins or 5-10 days? Haha
