but, I'm meassuring loudspeakers? jaaa doesn't
even have logaritmic
frequency scale, wich makes it kind of useless for the purpose...
It really depends what you're trying to achieve.
If you want to equalize PA systems, japa can be helpful, (using pink
noise); if want to create freq response plots or measurements, maybe you
should patch JAAA to add a log-scale option...
maybe you're actually looking for a different tool e.g.
http://www.baudline.com/
check the README of japa; it clearly states that it does filtering
("With the default settings, JAPA uses a filter set that closely follows
the Bark scale").
Fons - author of JAAA and JAPA - is on this list and may chime in sooner
or later.
