Can a PC be used as a graphic equalizer? If so, can you set up the
bands with any kind of octave combination you want? (customizable

Where would I find software like this?

My quest is to experiment with ways to use rooms and/or speakers with
difficult resonances. If, for example, a speaker box that might be a
little too small for the speaker,.. and the box resonance joins with
the speaker's free air resonance so the thing has an awful peak,...
would it be possible to suppress the signal somewhat at that resonance
peak with a customizable PC-controlled equalizer?

Thanks for any info,

You can't fix a time issue with a frequency fix. It's like pushing
down a ping pong ball into a bucket of water with your thumb, it just
keeps rolling around it. Someday the minds of dsp will realize this.

The other big problem is any EQ at 10 k hz or above with one octave or
more bandwidth in the digital domain will run up against Nyquist and
that will severly distort the phase response of the high frequencies.
Not to mention some pretty weird looking EQ curves as the bell on the
low side runs up against a brick wall at the high side of the bell.

Analog EQ's with wide bandwidth don't have this problem. It's probably
one other of many reasons why ITB sounds so small to me.
