In Pulse I just used the LADSPA module, and loaded it with
pactl load-module module-ladspa-sink. There is an example in the docs[0].
I stacked a number of filters on a null-sink and then used the loop-back module to put the sound from the mic into the top filter. Then I redirected mumble to the null-sink’s monitor. The filters I used were the ones I found in the debian package repo.
In comparison, it was much easier to do in JACK, where I could create the filter stack in jack-rack[1], which has a GUI,
and do the plumbing in qjackctl.
