Here is a free convolution engine that you can try and compare the
sounds it makes to my sample;

My sample: http://grimoire.genesismuds.com/perfect3.wav

The sound has gotten even better, and soon we will have an algorithm to
produce this sound without all of the hex editing done by hand, and
noise removal.

Tell me what you think of this cut please! And I'm interested in
finding out where I can get good sound effects that I can use with
vocoders and convolution engines. Thanks. Celemony seems like a good
option, but I'm interested in cool effects as well.
