I have read a number of "classical" papers about MDS and auditory

wondering if such experiments were still carried out).
I think the Gray/Wessel approach has failed.. it's too hard to figure
out what the results mean. (Just trying to be blunt to get your
attention. ;-) You start with convenient sounds, measure perception
and then try to figure out what the MDS dimensions mean. That hasn't
worked. I think that is why people have not been pushing on it very
hard lately.
Hiroko Terasawa and I have been taking an opposite approach. We're
*starting* with the dimensions, synthesizing sounds and then
measuring the stress between human perception and the pre-ordained
model. Several papers describing our initial results are online at

Sounds like Jim is doing something in between the two extremes.
