How are your filters implemented? If they are biquad or other similar
type that you can easily express as Z-plane poles and zeros, it's pretty
easy to generate a graph of the phase and amplitude response from the
locations of the poles and zeros.

Subject: Measuring phase and frequency response of a filter.
To: linux-audio-user <linux-audio-user(a)lists.linuxaudio.org>
Hi.
I'm building a little ear training application for eqing for which I'm
building some filter banks in puredata. Can someone point me to a
practical way of measuring and plotting my filter's frequency and
phase responses? Jack apps, pd patches or code should be fine.
Thanks!
