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!

PSP started the whole saturation in the box thing for me with PSP VintageWarmer many years ago, and they have gone on to build an awesome toolkit for us. I use it on every mix for sure. dzięki ! We love you guys!
