PSFLIB is a specialized audio library format created by Neill Corlett as an extension of the PlayStation Sound Format. It functions as a repository for shared samples and sequence data used by multiple PSF files, reducing redundancy in video game music archives. As a legacy format primarily used for emulation, it carries a low risk level because it contains only structured data for sound chips rather than executable code.
