Recently I tested all audio addons, which were updated during the last 12 months. Super Volume by Arimtak is a modern alternative to the „600% Sound Volume“-family of forks (e.g. lefriend, savva, 1fexd). In general they are all doing the same, but Super Volume is MV3 and replaces the usual tabs-permission with newer DNR – what may be helful in the future. The dev seems to be a fan of cartoons: There are animes in the popup and special host permissions for wcostream. As the latter is technically very chaotic, this addon works super stable on any less demanding site.
