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).

Sound Effects.  Again, I’ll stress that “royalty-free” ≠ “free.”  I’m as thrifty as the next guy, but I caution you against always seeking the free alternative.  A thing is frequently worth what you pay for it.  And, at some point, you expect others to pay for your work, don’t you?

Freesound.  I’m a particularly big fan of this non-profit effects swapping site.  The cost of downloading the sound effect you need is uploading a sound effect you have.

American Cinematographer, the monthly publication of the ASC, an indispensable archive of interviews with folks who explain their motives and techniques for creating images.

The American Society of Cinematographers (ASC) was founded in Hollywood in 1919 with the purpose of advancing the art and science of cinematography and bringing cinematographers together to exchange ideas, discuss techniques and promote the motion picture as an art form — a mission that continues today.
