Also removed spatialization, they reduce the quality of the sounds if these sound close or 2D

Spatialization should always be enabled for these but id be amenable to some volumetric area

First, sorry about having so many commits, it's been new for me to work with pull requests. In one of them I reduced the high pitched noise from the flying sound (now it should be more comfortable to hear)

Never worked with volumetric areas, so I don't know how they should affect, in my projects I prefer to sacrifice a bit of spatialization to have more quality, but if you want to prioritize spatialization I can set it as before

Bumping this PR, curious on your thoughts now @Happyrobot33 . I can do the distance testing etc if you need.
