@Segebodo @sirlan @miakizz some software also approximates it with the transfer function calculated for an average ear
i know minecraft has supported it as an official setting for a while and as an inofficial feature for a lot longer
but also i doubt this thing can give the same result as a good HRTF with headphones because it can't place the sound source physically directly in front or behind you, or above or below the horizontal plane at all, no?
