problem of front and back confusion

[kamrandemon]

Hi
i am actually working on a prototype to move a sound object around listener. I am successfuly moving the object and listener can identify easily the left and right position but when the sound is coming from front or back side it is very hard to be located. this is what they called front and back confusion. I am stuck to solve this issue. Please help me out how i can sort it out using joal
cheers

Unless you have a surround speaker setup, or a soundcard with a good HRTF capabilities, it'll be quite hard to solve with only left and right outputs.  All I can suggest is to make sure your listener is oriented the way you want (alListenerfv(AL_ORIENTATION, ...)), and if at all possible, create some sort of visual cue on screen to trick the person in the seat to believing that the sound is coming from in-front or behind them (a few speaker setup programs I've encountered have a symbol representing the sound source, circling what looks like the person's head, to indicate where the sound should be coming from).
