XEPOMAHT, Let me explain, the author of this plugin told me that it works correctly, it was created by reverse engineering of SoD and has not changed the volume of any sound. The original loopsounds sound correctly, an example I can give you is those from The Tides of War, but third party sounds that seem to have a low sound frequency seem not to be heard at high volume.

Not just any sound can be used as a loopsound and they can sound with the same intensity
