Is this gonna happen in our lifetime? :)\r\n\r\nJohn the parameter limitations of human hearing with respect to frequency response, phase, directionality, spatialization, etc has already been mapped, written about and published in many scientfic journals. A few sources have already been presented such as Everest, AES papers, Harman Research, NRC, etc. There really is no magic here.\r\n\r\nSeems like alot of effort on your part to measure the hair on a gnats a** :)\r\n\r\nI'll take your word on the hair...\r\n\r\nI've posted all my understandings, all my models, all my experimental design, on 5 different forums, in the hopes that someone would be able to speak on the topic with understanding...I have been pleased with some, and some have provided me papers or links or referrals that have been useful, which I thank all for.\r\n\r\nHowever, nobody has been able to answer these very simple questions:\r\n\r\nGiven a speaker placement and a listener position, what level of ITD and IID are necessary to place an image 30 degrees right of center stage, in the plane of the speakers? What ITD and IID are required to place the image a foot behind the first image. What parameters are necessary to move it 10 degrees to the left, a foot in front of the plane??\r\n\r\nThese questions are not answerable given the state of human hearing analysis I have seen to date..zippo...\r\n\r\nWhat are the JND levels for ITD and IID, by frequency and spl, for the entire 3 dimensional space?\r\n\r\nIf you have been holdin out on titles which can answer these questions, I'll hafta write a note to myself to be angry with you... :mad: \r\n\r\nSeriously, my discussion on forum is to try to find this stuff already published..I have had to resort to doing it myself only because I've yet to find anything useful..\r\n\r\nDon't even get me started on how poor power loads are with respect to accuracy...what a shambles...\r\n\r\nCheers, John\r\n\r\nPS...Is it gonna happen in our lifetime?....yes, I've outlines the timeframes involved..Unless, of course, I get bored with the entire subject, and direct my efforts in other, as of yet unknown, directions..
