Looks good, some questions:

1) Would it be easy to add one sample of how to use the kiss-ftt to calculate
the kernel?

2) in The doc-blob for 'element-audiofirfilter':
  2a) what is the relation of the configured latency and the number of
coefficients in the kernel (is there any). Or are there some guidelines for
setting a good latency. I mean just setting this to 0 would most probably not
work, but then nobody wants latency.
  2b) just link the first occurance of FIR to the wikipedia article and drop
the later link (same for iir).

3) GstAudioFIRFilter::rate-changed: Why is the signal needed. What about
notify::caps for the src or sink pad? Also isn't the signal dangerous, what
about a bus message.
