Hi Kai,
ok thanks for the information that compiled versions with ASIO support exist. When I had interest into this tool, many many years ago, I found none.
My recommendation is to invest either into a DAW with ASIO support (e.g. reaper or affordable entry versions of Cubase or other solid products) or if it should really only be something "easier" like a recorder / audio editor - to use google and search for: free audio editor ASIO. I found this free tool with ASIO support: https://www.wavosaur.com/, but I never used it, I would simply try.
There are also other tools available like vinylstudio/pro. If you buy a converter for €1700 then it should be tolerable to spend a few bucks for entry versions of DAW or such software, the basis version of vinylstudio is not too expensive.
I have no special recommendations, as am only using Cubase and Wavelab. Was only wondering why Audacity.
