SPL has been developing and manufacturing analog and digital audio gear for the music, film, multimedia, and broadcasting industries since 1984. SPL products are respected worldwide for their innovative approach and user-friendliness, but most of all for their outstanding performance.

The SPL Transient Designer is a world-wide studio standard just like the SPL De-Esser. The SPL Iron is a dream compressor, the SPL Vitalizer and the Passeq are analog legends. The new SPL Hawk-Eye is as geeky and detailed as a meter can get!

A highlight is the SPL DrumXchanger, a professional and easy (!) drum replacement tool that comes with samples as well! Get all of these serious tools and more in SPL's affordable brand-bundle. Scroll down for the complete list please.

Andrew Scheps (Adele), Josh Newell (Linkin Park, Avril Lavigne, Anthrax, Puff Daddy), Ethan Mates (Linkin Park, Red Hot Chili Peppers, Tupac, Tom Petty) are only a few of the many industry heavyweights using SPL plugins.

Hassle-free: all our monthly and yearly bundles will auto-renew every month or every year. This means you will be charged automatically until you cancel (which you can do anytime, of course), and your licenses will be renewed automatically every month or every year as well (depending on your specific plan).

    I use SPL plug-ins on every song I mix. They have everything from incredibly hi-fi compression and eq to super useful de-essing and transient shaping tools. What’s not to love?
