Tamas, I have sent you the Johannesma 1972 paper, the origin of the term "gamma-tone". I may have Schofield 1985 on paper some place, since I quoted from it back in '96; I'll try to find it if someone else doesn't. I haven't heard of the Lumer 1987 papers before, but they look good, and are available online for money. I might get... Eriksson & Robert 1998 is just an early version of Robert & Eriksson 1999 JASA, I think. All they say about it is "Previous versions of the model were pre- sented in Eriksson and Robert, 1998." They were among the few people who picked up on my 1996 all-pole gammatone filter idea and used it to make a good model. I'd be interested if you find it. If you're interested in the history of gammatones, a relevant often-overlooked paper is Dirk Van Compernolle's 1991 IPO report "Development of a Computational Auditory Model". It turns out he did the pole-zero decomposition of the gammatone, and the all-pole version as an approximation, a bit before Slaney did. From the Laplace transforms that he tabulated, he concluded, "From the above table it can be seen that an all-pole filter approximation will be excellent as long as alpha is small, i.e. for sharp filters, which is the case for a cochlear filterbank." It's easy to find online. Dick At 11:02 AM +0100 3/19/12, Tamas Harczos wrote: >Dear List, > >I am desperately looking for copies of the following papers: > >P. I. M.
