AES may not be the largest media convocation but it certainly is so in the world of Audio. You'll find not only all the top equpment manufacturers there but a great representation of newer and smaller vendors with quality hardware and software.
It's also noted for scientific papers and presentations by serious engineers (that's the E in AES, folks!) advancing the art and science of audio. For the less geeky theres a ton of lectures and expert panel discussions on the floor happening on two different stages, one for Live Audio and the other related to Studio Audio.
They've also got programs and meetings galore--organized into shubject tracks such as Sound For Picture; Recording and Production; Sound Reinforcement; Game Audio and more! AES has plenty of tutorial and workshop sessions—more than any one person could attend so the various 'tracks' are a great boon to help you organize your priorities.
We'll try to capture some highilghts for you but no doubt you'll be reading about the innovations and new products for months to come. Do make the effort to be there in person to get the most out of it. And if you run across us there say helloo!
