Jon Landau, producer of Avatar, talks about which and how Adobe software were used in production. He said nothing about sound, but that isn’t what I expect from Adobe anyway. It’s hardly to see Adobe Audition or Soundbooth was used for sound design of this kinda blockbuster flick.

Thanks @kajorn to recommend this video from Adobe TV via Twitter.
