PSP develops high quality audio effect and processor plug-ins. Our products garner rave reviews and endorsements from every corner of the music production, engineering, composition, and post-production worlds.  Our  plug-ins have become staples in professional and home studios worldwide.  Our credo explains our simple philosophy: It's The Sound That Counts!


For several years I´ve enjoyed using plug-ins made by PSP both on stage and in my studio. At some point I switched my onstage gear from hardware to using a laptop, and PSP made the transition painless by custom writing the patches I needed, and in a matter of days! Forever grateful!
