The Cinema Audio Society Awards are an annual awards ceremony that honor outstanding achievements in sound mixing. These awards are presented by the Cinema Audio Society since 1994.
The competition is open to feature films and programs released or aired during the calendar year. The winners are revealed in a sealed envelope ceremony during the Cinema Audio Society awards banquet the following spring. Winners are selected entirely by a written balloting of the C.A.S. active members.
Films marked with a dagger (†) won the Academy Award for Best Sound Mixing. Films marked with a double dagger (‡) were Academy Award nominees.
