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.
ciao,

robin
