Date: Sun, 23 Nov 2003 13:36:54 +0100 Hi, BruteFIR is very interesting, but its documentation is not sufficient to know how to convolve filters that use impulse responses. I emailed Anders Torger and asked him to give some hints how to do it, but he replied: Unfortunately, what you ask for is quite a lot of documentation, which I currently don't have time to do. It is a good idea to put it together sometime though, but I cannot do it now. So, If You have succeded by using it as a reverb. It would be very usefull, to give some more hints, how to do it.
