  • G2500 is a Compressor Library for Acustica Audio Nebula3 Pro
  • 192kHz, 96kHz, 88.2kHz, 48kHz, 44.1kHz
  • It was sampled and programmed in a way which allows ultra fast compression while still reproducing all the little nuances and characteristics of the original hardware and saving CPU!
  • Seperate Harmonic Distortion and Compression programs for the best quality with the least amount of CPU usage! (4 Kernel compressor programs also included)
  • Control over the amount of Harmonic Distortion independently from the amount of compression from clean to distorted!
  • Includes 3 LineAmp programs with different degrees of distortion, from subtle to heavily distorted!
  • Includes 4 Kernel Compressor Programs and 1 Kernel Compressor Programs
  • Inculdes Combo programs! (All ratios non-stepped within one program)

About the original hardware

This library is based on a very popular and versatile american compressor. It‘s most commonly used on busses, drums and for mastering but also shines on a variety of single signals like Piano, Bass, Vocals, Synths, Strings,  and everything else.

The sampling process

The compressor has been carefully sampled at 96kHz, using top notch mastering converters, and high quality cables with levels carefully calibrated and matched to provide the highest quality. No destructive digital processing like normalization was used. The 192kHz, 88.2kHz, 48kHz and 44.1kHz programs where re-sampled using one of the best sample rate converters on the market.
Audio characteristics and features.
This is a very versatile, fast, punchy and transparent compressor which can be used for a wide range of tasks in all kinds of musical styles. Its sound is very popular and can be heard on countless records. You can use it on single signals like Vocals, Drums, Guitars, Brass, Piano, Bass, Keyboards, on Busses or for mastering.
All programs feature the „Range“ parameter which controls an internal high pass filter to make the compressor react only to frequencies above the high pass frequency.
The „HQ“ versions offer higher quality while needing more CPU power.
The „SC“-Versions enable you to trigger the compression by an external sidechain for side chain compression or de-essing. 
The „EX“, „NC“, „ME“ and „NL“  versions can only be used with Nebula Compressor (Self modified copy of Nebula) and are in HQ by default (using TIMED engine).
The „EX“ programs offer the fastest compression behavior but depending on your computer, they might only work for rendering.
The „NC“ programs are very close to the „EX“ programs but need less CPU.
The „ME“ programs are a bit slower than „EX“ and „NC“ but use much less CPU.
The „NL“ programs are the perfect compromise between regular programs and „ME“ programs, with much less CPU usage and a little bit slower reaction time than the „ME“ programs. So for every scenario and available computing power, there is a perfect version to choose from. Choose what ever program version your computer can handle. The programs with „SC“ in their name are program versions for use with an external sidechain.
Tone Side Chain Filter 
It is a very special eq curve sampled from the hardware which produces a chest hitting punchy bottom end when the side chain gets filtered by it. Lower frequencies get compressed less than higher frequencies. The „Loud“ programs give you more of that effect than the „Medium“ programs. In order to use the SCF you need to instantiate nebula with a SCF program into the sidechain of a „SC“ compressor programs. How that works depends on your DAW. Here is one example: Send the signal you want to compress to two separate busses. On the first bus, instantiate nebula with a „SC“ compressor program, on the second bus, instantiate nebula with a „SCF“ program and send its output to input 3/4 of the nebula instance on the first bus.
After you finish the paypal payment process, you'll be immediately able to access the download links through your member account. It's recommended to use a download manager, which is integrated into your browser, so you can resume the download in case you lose connection.
Program List
All compressor programs are available as 4 Kernel and 1 Kernel versions, and also as PEAK, Fead-Back, Fead-Forwad, Fead-Back and Peak, Fead-Forwad and Peak, HQ-, SC-, EX-, NC-, ME-, NL- vesions. Also all programs are available in 44.1kHz, 48kHz, 88.2kHz 96kHz and 192kHz.
