The Postfish is a digital audio post-processing, restoration, filtering and mixdown tool
Around since about 2004, never had a release but does it's job very well!
Imported to pro-audio overlay in revision 2248, some modifications for CFLAGS/LDFLAGS and created tarball snapshot.
I added this to my overlay: https://github.com/kripton/kripton-overlay/tree/master/media-sound/postfish
