MItAC update

- rough notes on vinyl physics available here:
http://www.music.mcgill.ca/~deleon/phonograph_notes.doc
- above document will be updated regularly as readings continue
- main ideas from AES articles highlight imperfections of vinyl playback that inevitably lead to upper harmonic distortions, perhaps these can be avoided optically and then physically modeled back into the clean audio for a comparison study of preference
