I used this and some burning sound to create acid burn sound

I don't really know how copy left works so I will make my acid sound CC-BY just like yours (if you don't mind I'd like to make it PD instead) and leave a link to your sound. I think that I can waive my own rights to attribution but I can't waive yours but with your permission I could make the sound PD

EDIT: I just noticed you were not listed as the creator of the sound so never mind :)
