In Matlab, I have a room impulse response. I need to plot a frequency response from 20 to 20k Hz, smoothed to 1/3 and 1/6 octave. I can calculate the ISO octave center frequencies. I see lots of RTA software that does this real-time. Anyone have the Matlab code that does this, or provide the algorithm? Thanks.

Hi mikem, I used for many applications the "octave" package written by Christophe COUVREUR. You can find it on http://www.mathworks.com/matlabcentral/fileexchange/loadAuthor.do?objectType=author&objectId=802858 Bye, Marco mikem wrote:> In Matlab, I have a room impulse response.

Thanks Marco, I have tried to use this package. I'm starting with an impulse response and I believe this package looks for the original signal. Can I adapt the octave package to take an impulse response or process my impulse response into a form that the package can accept?>Hi mikem, > >I used for many applications the "octave" package written by Christophe >COUVREUR.

I used the package only with continuous signals, but I think that if you have a waveform with the impulse response it should work as is.
