Cycling 74
The home of Max/MSP/Jitter, need I say more. It also has a number of great links for the EA musician.
jMusic
A very good tool for the computer musician. The links and references pages are quite comprehensive.
Richmond Sound Design Ltd.
This page gives a whole lot of information about the products of the company, including the Richmond Audio Box. The Theatre Sound Designer & Resources Directory and the Bibliographies, Articles and Papers links are fantastic. 
AudioMulch
This is the site for AudioMulch, a very  interesting and extremely useful program. The discography page shows how widely it is used and the breadth of its applications. I use it as a significant part of my teaching and am regularly amazed at the variety in the work my students create with AM.
