AFAIK the University of Miami has the finest program in audio technology, but it would be a good idea to have a strong electrical engineering background along with music training for that one.
I was interested at one time in getting a graduate degree in Recording technology. (I studied recording tecnology in an Associate program at IU). By this time IU probably has a graduate degree in recording technology. When I was there, Jack Wilkins (he teaches somewhere in Florida now) was a grad student, and he had recording technology as a cognate field.
There are several universities that have grad programs in educational technology, which of course would include multimedia presentation.
There's plenty out there. Just find a place with a good fit.
