they're supposed to be faint originally
using ahigerd/agbplay-gui on windows 11
and those json settings:

Thank you very much, I'll look into it once I have some time.

I wanna extract all the music and sound effects from fusion in high quality

Must be something that the Metroid sound engine does differently than normal games. I can't really say how much effort this is to fix, since I don't really understand what has been changed.

I will of course leave this open, since it's unfixed. However, I won't give any promises to fix this any time soon.
