I recorded a live show where there are several instances of mic feedbacks. I
want to salvage as much as possible from those instances.

I have several audio/wave editors (adobe audition, soundbooth, audacity,
goldwave) at my disposal.

Most audio editors have notch filters, but to complicate things, the mic
feedback changes frequency slightly as it gets louder.

Is there a filter that automatically adjust to the frequency change and
remove the feedback?

Use Adobe Audition in spectrum view. You can draw around the squeal
with the lasso tool and delete it. Works seriously well. Filters are
too coarse and clumsy for this job.
