So I am trying to swap out music in K1 and eventually in K2. After researching online I read that you need to remove the track in question out of the Streammusic folder and replace it with an .mp3 of your choosing of the same name. I tried it and it did not work. I also followed this guide that had me download Audacity, convert the mp3 to mono, and reduce it to 22k Hz which made the track sound like garbage and still didn't work in game. I believe I am selecting the right track name because when I load into the area to test it there is no music at all, not even the default music. Is there an additional step I am missing? Do I need to make sure the mp3 file has certain properties? Any help would be appreciated!
