Don't know about current situation, but about a year ago I faced a need
to dereverbrate audio recording. I searched everywere and tested
everything I found, and two things below somehow worked for me. But
they are not related to ffmpeg yet.
1. https://github.com/helianvine/fdndlp
It is writen in python, slow, and possibly may require load whole file
into RAM buffer. But for speech it works well.
2. https://github.com/irungentoo/filter_audio/
It's writen in C, fast, but not as good as (1).
