OK, I read through the aliki docs, built aliki, and got it running. I'm away from my audio room so I can't actually play the sine sweeps, record the responses, etc. I also read through 8 presentations by Farina, referenced in one of the aliki documents. I've read 2-3 versions of the DRC docs all the way through over the years. I think I know how to get aliki to create an impulse response. But, I'm unclear as to how to use that as an input for DRC (digital room correction). I'm also unclear as to how to use the impulse response to get at things like RT60, clarity and the like. I *think* that if I could take the IR out of aliki and bring it into octave, Maxima, or Matlab, that I could figure it out from there. From the aliki docs it looks like exporting of files outside it's initial format is planned, but not yet implemented. Do I have this right? Another thing I might want to do is to have a look at a time plot including incident and reflected pulses. The time between those should be an indicator of the total path length between the source and the mic. By inspection of the acoustic space, then I ought to be able to figure out about where reflections are happening (thinking method of images) in that space and apply sound treatments accordingly. At least, that's my wistful hallucination. The pictures of impulse responses in the various docs I looked at weren't zoomed in enough for me to really tell what might be going on, and they were probably of real spaces, and not simple textbook rectilinear polyhedrons. I wonder, is aliki a tool that could help in this endeavor, if my idea is worth attempting at all. Aliki, and the direction it's going is quite exciting for me. I'm definitely going to stay tuned to this channel.
