The filter_audio API is not working for qTox/Tox and thus disabled by default via compiler switch. In current qTox UI, it is not configurable, even when this switch is enabled. According to issue #3194 the library is no longer maintained as well. I don't see any reason to keep it in qTox.pull/3351/head
