I was wanting to create morphing sounds in csounds. I did it before with pure csounds using the (LPC)Linear Predictive Coding utils lpanal. I read though that loris is much better at creating sound morphing. I could not get loris to work either as a stand alone utility or as a part of csound. The last release of loris seems to be about a year ago. Is it still being maintined. Is LPC just as good. I am not sure I understand the difference. I read through the docs and it explained that it was different but just described what I thought was the same process LPC. If Loris is better perhaps I will have to try to fix the problems with loris. Here are the errors I get when doing loris stuff in csound: ERROR importing SDIF file: Runtime Error -- File i/o error -- Could not initialize SDIF routines.
