Good morning experties, I'm using Levinson-durbin algorithm to invert room impulse responses. I used the MAtLAB code writen by Bob Cain in the following page http://www.musicdsp.org/showone.php?id=188 The code works well, but I can't understand why it works! The following equation should be solved : R*hinv = q Where R is a Toeplitz matrix, hinv the wanted inverse filter and q is a well known vector. Can you please help me to understand how this code works! I will be very gratefull. Thank you Stef

I'm I understanding that you are doing something with acoustics here? What is your objective in inverting this impulse response?
