Audiocrunchie
Hi,

For my DSP class I have been asked to find research papers which deal with technical comparison and analyses of audio on CDs vs. Vinyl.

Can anyone please point me to a place where I can get those?

Forgive me for a newbie, low tech question but I'm desperate! crying.gif

Thanks
Jim

There was a good book at my university library about it. It was in French, but it was so huge an electromagnetic course that it might very well exist in engligh. It was called "Traité d'éléctricté de l'Ecole Polytechnique de Lausanne" (ou "traité d'éléctromagnétisme"), a somewhat 20 volumes of physics courses aimed at 3rd to 6th grade students. One volume speaks about electroacoustics, and there is a chapter about vinyl. It describes the problems of turntables : speed accuracy, electromagnetic shielding, mechanical isolation, and stylii shapes : spherical, elliptical, linear contact, speaking about contact surface, tracking error etc.
I hope you can find it in your university library.

We performed frequency response comparisons, and there is a dynamics coparison too. Keep in mind that the differences measured can very well be caused not by the media, but by the mastering engineer preparing the master for the media.

I wanted to post the link to a page about mastering vinyl that I already linked here, but I can't find it back. The words "vinyl" and "mastering" are used every two days in these forums ! I searched to web without success (BTW, I found lots of pages dealing with the loudness race). It was a page of advices for the mastering engineer, dealing with the limits of vinyl cutting, and how the master should be processed so as to comply with them. If someone bookmarked it when I posted it, please post it here smile.gif

Old AES journal articles are probably worth their weight in gold here. Even some modern articles have lots of good background material on vinyl technology, and good references. Hunt them down in your engineering library and devote a few hours to paging through them - good stuff.
