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!

Once again, PSP have raised their game, and PSP Neon and PSP Neon HR are both excellent-sounding EQ plug-ins that offer sweetness and transparency. Linear phase plug-ins are deliberately smooth and neutral in character, which makes them perfect for mastering, but they still all sound slightly different. For me, PSP's Neon HR has an 'analogue' quality that makes it shine.
