I understand that to add more range to the sound you have to edit the unity3d, now you have to be glued to the machine to hear it well if you move away you can no longer hear it, but the file unyty3d I understand that is locked and can not be edited.
cooljuke10 is a lot of fun but you can only listen to it if you are on top of it, you can't extend the range in which you listen to the music.
