THX TASA Trailer Certification
TASA (Trailer Audio Standards Association) is a sound standard for motion picture trailers that was originally developed and adopted by representatives from Disney, Dreamworks SKG, MGM, Miramax, New Line, Paramount, Sony, Twentieth Century Fox, Warner Brothers, and Universal, and by technical representatives from Dolby Laboratories, DTS, Sony Cinema Products Corporation, TMH Corporation, Fultek, and Westwind Media. It is administered by the Motion Picture Association of America.

The TASA standard’s intent is to equalize the sound volume of theatrical trailers so that they come close to matching the volume of the features that they precede.

Compliance with the TASA standard is now required by the MPAA Advertising Administration through its advertising regulation.
