Nebula3 Pro Bundle: A Closer Look




Nebula3 Pro (CoreII Engine): The Multi-Effect Plugin




Nebula3 Pro is the core component of the Nebula3 Pro Bundle. It is a multi-effect plugin that can emulate and replicate various types of audio signal processes using Vectorial Volterra Kernels. These are mathematical functions that can describe and model the nonlinear behavior of analog devices, such as distortion, saturation, compression, etc. Nebula3 Pro uses libraries that contain these kernels, along with other information such as frequency response, harmonic content, dynamic range, etc., to create realistic and complex emulations of real hardware units.


Volterra Kernels Series: The Technology Behind Nebula3 Pro




The technology behind Nebula3 Pro is based on Volterra Kernels Series, which are a way of representing and analyzing nonlinear systems using linear operators. A nonlinear system is one that does not obey the principle of superposition, which means that the output is not proportional to the input. For example, a guitar amplifier is a nonlinear system because it can produce distortion and harmonics when the input signal is too loud. A linear system is one that does obey this principle, such as a simple resistor or capacitor.


Volterra Kernels Series are a way of decomposing a nonlinear system into a series of linear operators that can be applied to an input signal to produce an output signal. Each operator is called a Volterra Kernel and has a different order and dimension. The first order kernel is equivalent to a linear system, while higher order kernels represent nonlinear effects. The higher the order and dimension of a kernel, the more complex and accurate it is, but also more computationally intensive.


Nebula3 Pro uses Volterra Kernels Series to capture and reproduce the sonic behavior of analog devices. Each library contains a series of kernels that describe how a device reacts to different input signals at different frequencies and levels. By applying these kernels to an input signal, Nebula3 Pro can recreate the sound of the device with high fidelity and detail.


CUDA Processing: The Performance Boost for Nebula3 Pro




One of the challenges of using Volterra Kernels Series is that they require a lot of CPU power to process. This can cause latency issues, glitches, or crashes when using multiple instances of Nebula3 Pro or other plugins in your DAW or editing software. To overcome this problem, Nebula3 Pro supports CUDA processing techniques that can offload some of the processing tasks from your CPU to your GPU (graphics processing unit).


CUDA is a parallel computing platform and programming model developed by NVIDIA that enables GPUs to perform general-purpose computing tasks. GPUs are designed to handle graphics-intensive tasks such as rendering images and videos, but they can also be used for other types of calculations that involve large amounts of data and parallelism. By using CUDA processing techniques, Nebula3 Pro can leverage the power of your GPU to run faster and smoother, while freeing up your CPU for other tasks.


To use CUDA processing with Nebula3 Pro, you need to have a compatible NVIDIA GPU card installed on your computer and enable it in the plugin settings. You can also adjust the amount of CUDA cores that you want to use for Nebula3 Pro, depending on your system resources and preferences.


Commercial Commercial Libraries: The Sound Collection for Nebula3 Pro




Another important component of the Nebula3 Pro Bundle is the collection of commercial libraries that are included with the plugin. These are sound presets that are created using the N.A.T.3 tool, which we will discuss in the next section. The commercial libraries offer hundreds of different real hardware emulations that cover various types of audio signal processes, such as EQ, DYN, REV, etc. These emulations are based on accurate measurements and analysis of vintage units from various brands and models, such as Neve, SSL, API, Lexicon, EMT, Studer, Ampex, and more.


The commercial libraries are organized into categories and subcategories that make it easy to find and select the sound that you want to use. You can also browse through the libraries by manufacturer, model, or type of device. Each library has a name and a description that tells you what it is and how it sounds. For example, you can find libraries like "AlexB Modern White eQ", which is a modern mastering equalizer based on the Weiss EQ1; "CDSoundMaster R2R", which is a tape emulation based on various reel-to-reel machines; or "Henry Olonga G-20", which is a guitar cabinet simulation based on the Marshall 1960A 4x12.


The commercial libraries are constantly updated and expanded by Acustica Audio and third-party developers. You can also purchase additional libraries from the Acustica Audio website or other online stores. You can also create your own libraries using the N.A.T.3 tool, which we will explain in the next section.


N.A.T.3: The FX Sampler




N.A.T.3 is a standalone tool that is included in the Nebula3 Pro Bundle. It is an FX sampler that allows you to create your own libraries for Nebula3 Pro using your own audio devices or any other sound source. N.A.T.3 stands for Nebula Advanced Technology 3, and it is the latest version of the tool that has been improved and optimized over the years.


Sampling Approach: The Methodology Behind N.A.T.3




The sampling approach that N.A.T.3 uses is based on a methodology that involves three main steps: input, processing, and output. The input is the sound source that you want to sample, such as an analog device, a digital plugin, a musical instrument, a voice, etc. The processing is the action that you want to apply to the input signal, such as equalization, compression, reverb, etc. The output is the result of the processing that you want to capture and reproduce using Nebula3 Pro.


To create a library using N.A.T.3, you need to follow these steps:



  • Connect your input source to your audio interface and select it in N.A.T.3.



  • Select a processing type from the drop-down menu in N.A.T.3. You can choose from different categories and subcategories of audio signal processes, such as EQ, DYN, REV, etc.



  • Adjust the parameters of the processing type using the knobs and sliders in N.A.T.3. You can also use the buttons on the bottom to access more options and settings, such as input and output levels, latency, quality, etc.



  • Click on the "Sample" button to start the sampling process. N.A.T.3 will generate a series of test tones that will be sent to your input source and processed by it. The processed test tones will be recorded by N.A.T.3 and analyzed to create Volterra Kernels Series and other information that will be stored in a library file.



  • Save your library file in your Acustica Audio folder and load it in Nebula3 Pro to use it.



Convolution Techniques: The Tools Behind N.A.T.3




The tools behind N.A.T.3 are based on convolution techniques that are used to create impulse responses (IRs) from test tones. An impulse response is a recording of how a system reacts to an impulse signal, such as a click or a sweep tone. By convolving an input signal with an impulse response, you can recreate the sound of the system on any sound source.


N.A.T.3 uses different types of convolution techniques depending on the type of processing that you want to sample. For example, for time-invariant effects like equalizers or filters, N.A.T.3 uses sine sweeps or logarithmic sweeps as test tones and performs fast Fourier transform (FFT) convolution to create IRs. For time-variant effects like reverbs or delays, N.A.T.3 uses exponential sweeps or noise bursts as test tones and performs time-domain convolution to create IRs. For nonlinear effects like distortion or compression, N.A.T.3 uses harmonic distortion analysis (HDA) or dynamic convolution to create Volterra Kernels Series.


By using these convolution techniques, N.A.T.3 can create accurate and realistic IRs and Volterra Kernels Series that can be used by Nebula3 Pro to emulate and replicate the sound of any audio device or process.


Sampling Possibilities: The Potential Behind N.A.T.3




The potential behind N.A.T.3 is that it allows you to create your own libraries for Nebula3 Pro using any sound source that you have access to. You can sample your own audio devices, such as analog gear, digital plugins, musical instruments, microphones, etc., and use them with Nebula3 Pro. You can also sample other types of sound sources, such as natural sounds, ambient noises, sound effects, etc., and use them to create new and unique effects with Nebula3 Pro.


By using N.A.T.3, you can expand your sound collection and customize your sound palette according to your preferences and needs. You can also share your libraries with other users and explore the libraries created by others. You can also purchase additional libraries from the Acustica Audio website or other online stores that offer high-quality and professional libraries for Nebula3 Pro.
