Lowpass (linear phase) filtering of the response. Or windowing the
IR which is equivalent.

If you window the IR, you get a constant resolution over the
entire range of the FR. To get a variable rate such as 1/3 oct,
you need frequency dependent windowing - the window gets shorter
as frequency rises. It's not easy to do right (one of the reasons
why aliki still isn't finished).

IIRC DRC can produce such plots if you ask it nicely.

Hi, Fons!

I have got from DRC mailing list a suggestion to play with octave scripts.
After some thinking I have decided to play with python as such funny games
potentially may be more usefull for me (probably it's my mistake :-)).

Thanks, I'll think what does windowing mean.


Happy aliking!
