N4 is a multi-effect plug-in that emulate and replicate several types of expensive audio equipment, eliminating the need for costly and bulky hardware. N4 uses libraries which are created using a sophisticated "sampling approach" making it possible to "record" aspects of the sound of audio devices and play them back. The result of this sampling process is highly realistic, complex emulations of many types of audio signal processes, captured and utilized all within a plug-in that is compatible with all major DAWs and editing software.

About Acustica Audio:
Acustica Audio is a company that is active in the field of information technology and audio engineering. The company's goal is to provide the most authentic reproduction of sampled vintage gear and other high-end hardware devices. Over the years it has become well known for audio plug-ins, by manufacturing its own software products and marketing them both in Italy and worldwide. Acustica technology is based on a software engine of DSP (Digital Signal Processing) developed by Acustica Audio that emulates other DSPs, by modelling them through a proprietary sampling technique. Unlike the audio sampler, which is an electronic musical instrument able to capture and reproduce audio samples, Acustica technology can sample and emulate the behaviour of an audio processor, by reproducing its harmonic response, harmonic distortion and dynamic response as time and other external variables (like user controls) change.
