Do I need to know about the academy rolloff ?
Well, although it is a holdover from film sound’s infancy, we need to be aware of it, since it does have some relevance in certain circumstances. The academy rolloff is a specific frequency response curve that is used in dubbing stages to simulate the effect that the old-time optical soundtrack would have on the frequency of the final soundtrack. With advances in technology in today’s film industry, its use is diminishing, although it has been used on mono theatrical trailers to this day. How do I get more info about Surround Sound Licensing? It would be best to consult the various vendors themselves… THX can be reached at http://www.thx.com/thx/thxmain.html, or in San Rafael, CA through 415-662-1800 Dolby Labs can be reached at http://www.dolby.com, or locally in L.A. at 213-845-1880 Digital Theater Systems can be reached at http://www.dtstech.com,or locally in L.A. at 818-706-3525 Sony Corporation maintains a web page at http://www.sony.com Ultra*Stereo Labs can be reached directly
