The late Ray Dolby will be honored at the 50th annual Cinema Audio Society (CAS) awards for his contributions to motion picture audio technologies. The tribute will include rare video footage of Dolby accepting the Life Achievement Award at the 1989 CAS awards.

Dolby, the founder of Dolby Laboratories, holds over 50 U.S. patents and his technologies are still used by recording artists and filmmakers today.

“It seems fitting in the 50th year of the CAS, that as we award the latest in Technical Achievements for production and post-production sound, we pause and remember Ray Dolby, a true pioneer of the sound community,” CAS president David Fluhr said in a statement.

The 50th CAS Awards will be held on Feb. 22.

Dolby will also be honored by the Motion Picture Sound Editors (MPSE) at the Golden Reel Awards on Feb. 16.
