The Free Ranger is based upon the Full Ranger-EQ from SPL’s EQ Rangers series. It features four very useful bands: The 16 kHz center frequency band is great for adding very pleasant brilliance; the 1.8kHz center frequency band really brings out lead vocals and guitars or reduces harshness; the 150 Hz center frequency band adds warmth, making tracks fuller & fatter, while the 40 Hz center frequency band adds that sub thump or reduces rumble.

Once you’ve grabbed your Free Ranger, you’ll want to demo the SPL EQ Rangers bundle which includes three 8-band EQs: Vox Ranger, Bass Ranger and Full Ranger. Like all Plugin Alliance products, they’re available as 14-day full function demos and no dongle is required!

The Analog Code
During listening tests of this technology, a hardware developer remarked that SPL had “cracked the Analog Code!” and in the process, coined the name of SPL’s software product line.

SPL hardware products can be found in the world’s most renowned facilities, and have become a staple for audio professionals ranging from home studio owners to top mastering engineers. With the growth of computer based audio systems, the need for the SPL sound in plugin form has also grown. With Analog Code plugins, that coveted SPL sound is now available right inside your DAW.

Go get it, it’s free!

    Cool have been cool, but too limited

    I like the sound of it, but you have so little control that it makes it unusable.
