extract sound files or replace them?

[bernd1]

What exactly does "dump audio" mean? Put it out of the iso?

I tried to open the iso files with winrar and some other apps and they told me that they can't handle it. Now i opened Dolphin and clicked on properties and I can see a folder called sound. The files inside there are a msm and a pdt. I extracted them but now I don't know how to continue.

edit: I found this vgmstream, I'll try to figure out how it works.
