Octave Smoothing

Started by mikem May 23, 2006
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

Bye,

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?

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.
