Title: Interesting papers about time domain in music and transient importance Post by: Telstar on July 27, 2009, 04:42:01 pm Several of this points are known, thought by Peter, myself and others who frequents this forum.
http://www.physics.sc.edu/kunchur/Acoustics-papers.htm There are discussions open on the asylum, stereophile and hydrogenaudio forums (i stay away from the latter 2) http://www.audioasylum.com/cgi/t.mpl?f=prophead&m=54733 A couple of notable points: "There are no periodic signals in music. Everything has a starting and stopping point, and a lot of it is transient behavior. This hits at the very flaw of Nyquist/Shannon theorem." Multitone signals are already 10 times better (to measure THD for instance), but lots of work has to be done in this subject. I also know a person who confutes Fourier theoreme, because of time variancy (with digital sources).

This is really interesting stuff. One of the most valuable lessons for me is that 'anecdotal' is valid (and this from a credible scientific researcher). Keep the faith Peter... Mani. |
