SFZ tools is an organization built to foster communities around SFZ instruments, an open and human-readable format used to described synthesized or sampled sounds. We work in particular on sfizz, an open-source implementation of the SFZ format that can be used as a plugin in digital audio workstations, or as a library to integrate in various other software.
