Interesting - I found the letter through the Uni's electronic journals
access. Peter used both "ambisonic" and "ambiphonic" ( _not_ "Ambiophonic"
!) in that letter. However, I was then able to go back to his letter in the
Feb 8 1973 of that Journal and found that that one also contained
"ambisonics" and, not only that, but it also discusses the use of phase
shift based matrix technologies to get two channel representations (ie
what became uhj) - moreover the letter is actually dated November 1972!
