okay, check Rogalsky's website because this is quite interesting in terms of "what is silence" in the sense of Cagean questioning....
Rogalsky says of the CDs: >Documentation will include technical details of signal strength and silence threshold throughout the day.< This makes me assume that his method of extracting silence simply consists of extracting those signals whose amplitude is significantly below that of the normal amplitude of speech or music (i.e some silence threshold) during the broadcast. This is Cagean silence but not real silence. In fact Rogalsky could have extracted real silence (i.e. moments of zero amplitude, of course this assumes there would be some) using this method because of the technology he's using.......would that have been more interesting? Anyway this Rogalsky seems pretty interesting so thanks for the link. I read more about him at http://www.silenceisntgolden.net/ (limited doc for radio project) http://mrogalsky.web.wesleyan.edu/ (docs of various of his projects) cheers, Sol.
