I had a page on ambisonia.com with a lot of what has been discussed and was trying to find it before Jerry, who provided much of the info, noticed our discourse.
Unfortunately ambisonia.com seems to be unobtainium. I know this has been asked before but is ambisonia.com archived anywhere and will it be available again? I'd like to thank Jerry for posting even more details of the history of this fascinating subject. Transaural (ie Jerry) are definitely the originators of the 2 most important concepts; speakers close together and having the bass units further apart. These turn xtalk cancellation from a fancy technical exercise to something which promises better performance. Robert Greene was the first to suggest a physical barrier but I don't think having your nose stuck to a vertical mattress is as elegant as the Greene/Lee neckbrace. One of the points I made on my webpage is that x'talk cancelled "binaural" over speakers is a SURROUND technology needing only 2 'speakers' but the encoding is complex. Answers to the encoding question are invited. I'll second his reminder of Dr. Duanne Cooper's role in the birth of Ambisonics. His name appears on the patents and Michael always spoke highly of him and his contribution. Jerry, Eric Benjamin mentioned that he'd found a commonly used set of HRTFs (KEMAR I think) flawed. I think this is why he prefers spherical head models. Have you a recommendation for a publicly available HRTF set? _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
