Bruno,

Thanx for qouting the excerpt from DSP. That speaks on how to locate azimuth of the source. What about elevation. I mean how does ear or brain sense that sound is coming from ground or sky, if listener is standing at a height.

Regards.

PS:

Yah, its absolutely off topic. But let's not be tooooooooo... strict on 8052 related stuff only. Lets encourage and help eachother on "off topics" also which are likely to yield a project that will "Strictly" use an 8052 or a varient and that can eventually become an 8052 based project by its title in this forum.
