I'm actually a really proud user of Tomassini's Sound Solution DSP (http://winampheritage.com/plugin/sound-solution/120741), to process real time audio coming from sound card line-in, been processed and then played back to line-out for live recording, karaoke and so on.
But sound solution has 2 big problems, the first one is that it is an old winamp plug-in (and winamp is no more an active project), and the second one (BUT the worst), is that it runs on windows
So i was searching for a similar, linux, open source project, but i have not found nothing like that, simple and effective.
Stereo Tools (http://www.stereotool.com/) is interesting, runs on linux also, have a free version, BUT is not open source.
So i was thinking about some kind of premade setup script for CALF or a similar.
Do someone know of something easy and effective (maybe also able to run on raspberry pi3 or other powerfull enough SOC)?
Thanks for you time, and your efforts
