The Cinema Audio Society consists of Sound Mixers and Associates from the Film and Television Industries. The Society was founded to create a proper channel of communication between the related sound crafts and between those instrumental to the production and distribution of film and television soundtracks.

The CAS Awards for Outstanding Achievement in Sound Mixing are presented annually to the winning Re-Recording and Production Mixers in each of four categories: Television Non-Fiction, Variety or Music Series or Special; Television Series; Television Movies or Mini-Series; and Motion Pictures. The competition is open to feature films and television programs released or aired during the calendar year, and the winners are revealed in a sealed envelope ceremony at the Cinema Audio Society Annual Awards Banquet.

For the 2010 CAS Awards the SoundWorks Collection partnered with the CAS to provide exclusive backstage interviews with the winners of this years awards show.
