Descriptions for Acustica Audio Nebula 4 v2.2.1 External Libraries

N4 is our fastest-processing, best-performing, plug-in creation yet, a multi-effect plug-in in VST, AAX, and AU formats for macOS and Windows.

N4 emulates the character and personality of analog hardware with exacting accuracy, allowing you to emulate and replicate several types of expensive audio equipment, eliminating the need for costly and bulky studio hardware. Whether it is high-end outboard equalizers, classic compressors, the latest reverbs, or vintage time-variant effects like phasers and flangers, N4 has them all. Experience the full power of our proprietary audio processing technology, based on Vectorial Volterra Kernels, and find out what Nebula technology can do for you!

Developer Website

This version runs only unprotected nebula libraries (that you can find on this site), and comes with no library on its own. Now you can test and support the respective library devs directly without purchasing the full N4!

There is no need to block internet to this plugin. But if you have purchased other Acustica products and is running Aquarius online, use this release at your own risk.
