I'm I understanding that you are doing something with acoustics here?

What is your objective in inverting this impulse response?

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
