The Cinema Audio Society (CAS) was formed in 1964 for the purpose of sharing information with Sound Professionals in the Motion Picture and Television Industry.  Active Members are Mixers (Production and Post Production, Film and Video) who work on Feature Films, Television, and Commercials, as well as Mixers who specialize in Music Scoring, Video Post Sweetening, A.D.R. and Foley.  Associate Members are Sound Specialists, such as Sound Editors, Technicians, Recordists, and Microphone Boom Operators.

Royalty-free Production Music.  Be advised: “royalty-free” ≠ “free” music.  Some of these sites offer music that may be had for free in exchange for acknowledgement in the credits.  Others offer music for sale.  Please do not confuse one with the other.  Worse, do not illegally appropriate (a.k.a. “steal”) music.  Doing so constitutes a violation of the university’s academic honesty policy (for starters).
