Sadly not.

We have treble, bass, and mid range. The mid is switchable between 1 & 2
Khz.
The "MDB" is quite a complex doo-dad that tricks the brain into hearing
frequencies that the speaker cannot produce - more about this in the
Audio_3587 documentation.

Audio_3587 is my little plugin GUI which controls MOST of what can be done
with the DAC ...the only thing not in there is (afaik) the Karaoke feature
on the DAC which I had planned to do as a seperate plugin with +cdg support.

It's only compiled up with 2.2 right now, but if you want to play with it
you can pull it off my website
http://homepage.ntlworld.com/cyborgsystems
If it can help you solve your problem then yes it is possible - if not,
then no.

The other thing is, that it seems you are wanting to loose about the only
batch of frequencies that have no direct control - have you tried upping
all the others and turning the volume/gain down? ...again, if you know
what frequencies are boosting by name, you may also find the fine control
on the gain in Audio_3587 to be beneficial to your challenge?

Enjoy,

BC
