N.A.T.3 Gear Sampler

N.A.T.3 is a revolutionary professional tool capable of sampling nearly all forms of audio effects processors. The concept of sampling used to be limited to sounds. With N.A.T. (Nebula Application Tools) we have now made it possible for the process of sampling to include FX units. N.A.T. can sample software or hardware, analog or digital, combining various unique convolution techniques (linear, non-linear, and time variant). N.A.T. is able to replicate the original sonic behavior of vintage units like pre-amps, equalizers, tape devices, guitar and bass amplifiers, reverbs, microphones, cabinets and any time variant device like chorus, flanger, tremolo, phaser, Leslie cabinets, and more.

Audiofanzine FR's review

Acustica Audio Nebula 3
(Originally written by Rouxxx/translated from Audiofanzine FR)
First install the program, then all libraries and then the updates...

Elaborate configuration.

The software is still under development and you can download CUDA drivers to use the processing power of your graphic card and reduce the load on the CPU.

It's not really plug'n'play!


With my Core2duo E4600 the resource consumption is very high.

The CPU usage is much lower with multithread DAWs and considering the resource consumption it's not a plug-in you would insert in every channel, but I wouldn't mind doing it though!!

The plug-in runs quite stable on my computer.


I've been using it for over one month, mainly as EQ and tape saturation and more recently as a compressor.

The quality and sound character of the EQ are amazing.

You get EQ responses from many different vintage analog mixers (Neve, Api, Brent Averill and many more).

Its main turnoff is the CPU usage so you'd better have another good and less demanding plug-in as a second choice!

The best solution would be a DSP card.

I also like the compressors, but the models provided color the sound too much and some of them aren't that easy to use.

The plug-in also provides amp, preamp and reverb simulations but they aren't as interesting. The reverbs load the CPU too much and I already have many convolution reverbs.

Value for money:

Version two is very cheap.

Version 3 is also inexpensive.

I wouldn't hesitate to buy it again.

Acustica Audio Nebula 3
L'installation est-elle faite sans problèmes?
L'installation a été très facile.
Si jamais il ya des difficultés, la «nébuleuse communautaire» est prête à aider sur leur forum ...
Pour ma part je n'avais pas de soucis.
La configuration générale est facile?
Il est simple. Maintenant, quand à installer de nouvelles bibliothèques (CDsoundmaster, AlexB ..) doit déplacer les fichiers manuellement (un manuel est fourni avec chaque nouvelle «bibliothèques»)
Avez-vous rencontré des incompatibilités?
Le manuel est clair et suffisant?


What are the system?
MacBookPro 2011, Imac 2009, a great room treated !!!!, Apogee converters, TLA Fattrack, KRK VXT 8)

The software works he correctly on this configuration?

Yes, but Nebula takes bc bc of RAM (it re-sample your audio file ..)
(A x installed on your computer, with you 3 and nebula Nebula Reverb. The nebula reverb takes fewer resources, and it works perfectly with the EQ presets, PRE, ect ..) So to relieve the computer I ' utulise Nebula as reverb.

For my part, during the mixes, I leave no plug nebula (a hand on to) when I insert sets, I load my presets, the rule, and I export the track quickly (Bounce in place) , then I move on. I call them "track x - EQ / PRE 1" if I ever did change, "track x - EQ / PRE 2" ect. That way I know tj go back in time ..

In fact, it's just impossible to puff in the same way as other plugins. For me, it's not a plug Nebula is a platform ..

Basically, if you are patient and organized is perfect.

This software + hardware is stable?

Yes. For me it's perfect. Under Logic better. I have pro tools 9 and ADC (automatic delay compensation) is - powerful than Logic Studio.


What is so special that you like most and least?

The sound is excellent. Before I had a small room not treated with a digi 002 and Rockit stuck to the wall ... (The sound seemed good but not +. In fact you really have to work his ears and have super good listening and converters.

On presets:

Acustica Audio:

-The steps are good
-Filters very impresionante
-FX ("time variant") cool
EQ-few are really worth!

CDsoundmaster (

Focalpoint-115HD (ISA 115 HD, circuit design by Mr. Neve): very pleasant in the low mid, not aggressive when it boosts the high frequencies. Superb PRE / EQ..Superbe to catch votes.

The GEQ-8200 (GML 8200): Perfect for group or buss mastering. Low and High shelf impressive! my favorite preset: boost wide (wide bell @ 26kHz)

-N-TEN-AT4 (1084 eq) EQ for my snares! PRE great for vox, el. great for guitar punch.

-W295B (W295B Siemens): My favorite preset: High shelf. it's the best I've heard high shelf. Perfect on vocals and mastering.

EQ-Q8 (444X Quad Eight EQ) EQ for my tracks tt tt my mixes:)

R2R-Tape Collection + booster (Studer A800 mk III, Otari MTR-10, Studer Revox b77, ect combined with diff tapes: Ampex ATR, etc) Very good range of sound, since I use them I have less need compression and EQ. (Utulisation: you load your preset tape, say OTR 499 0dB, then you support Tapebooster (harmonic distortion generated by Nebula but still boosted +, for an effect like "bloated")

-Vintage collection tubes + Tube Booster: Superb. G Fattrack one, and I find the same sound, except the background:) (tubes: Mullard, Radiotechnique, Amperex, Brimar ..)

AlexB (

-Vintage Black EQ (api550a) Not bad at all on the Drums!

Tube Pre-Modern (Electro Harmonix, BugleBoy, MullardJAN / Philips, Tung Sol, ect) Still tubes ... Beautiful colors, whether the master Buss (MIC presets generate less harmonic distortion than the presets LINE)

Preamp-Color Suite: So the joke is: Trident S80 Channel Strip, API 512, Amek 9098, AMS 1073, AMS 1081, Avalon VT737, Fatso, Neve Portico 5012, Telefunken V72 tube & solid state, SSL VHD (5 presets!), ...

I utulise tt time, mid bc I know the time has different characteristics of each sampling, but it's going mnt. I know when and why to. Especially for the "Libraries", you have to have a listen and play pro.

Suberbe on synths. (Not VST)

-4KD (SSL dynamics 4000): comp slices of consoles and master buss. just without comp, the low mid is a pleasant listen + c odd. side of the comp, it is very natural. It's just that when it is removed there sth wrong. To me it does not sound like a plug!

RoomHunters Theater of Life

Best reverb I've heard in the plug. listen to the bounces on their site!

How would you rate the quality / price?
Great for the range of "colors"

With experience, you do again this choice?
Yes but not the madness of buying as many "libraries" of other vendors.
just R2R, Vintage Collection Tubes, Quad 8, 4KD, W295B, Black Vintage EQ .. . In fact ... I do not regret it:):) !!!!!!

I confess to the bounce in place all over the place, it's not fun, but ultimately it sounds. I tried to make mixes fast (fast in the sense of "work-flow) with a bundle of Waves but I was quickly frustrated because the sound I had in mind was not what I heard. It's not fun koi .. So I prefer to have trouble with the mini Nebula and have superb sound in the end.

Sometimes I replay my mixes and I'm almost convinced that I used at least one rack "high-end"! It's a good sign.


otavioreis's review (This content has been automatically translated from French)" good and cheap option"

Acustica Audio Nebula 3
I had heard about bcp nebula few years ago and that's good. I decided then to get started.

The problem is that the site was messy. I do not know how it goes today, but at the time of installation and configuration was really special, if complicated.

Although it is a music software, I think that Nebula had to be done by computer scientists for computer scientists.

I did not find any inconsistency, but I struggled a bit to install it.


good, I have a hyper i7 with all powerful.

I use version 64 of Nebula, but I feel it is still greedy and sometimes the performances are not great. But there's no bugs.


The big advantage is its Nebula value for money.

There bcp bookstores. Some are very good.

The sound is really good for not very expensive. However, it eats up CPU.

Pat One's review (This content has been automatically translated from French)" Beware: = top but its use = flop"

Acustica Audio Nebula 3
At the time I bought Nebula was a nebulous concept enough .... Since it appears that the site was redone, it looks a bit clearer, but it's not obvious how it works without trying the beast, for it is a plug-in rather special. No big installation problems.


PC i920, 8GB RAM, Cubase 5, RME HDSP 9632.

Good software is very resource intensive, it seems that optimizations have been made over time, but it's still cumbersome to use, since the concept ... I did not experience significant bugs.


I use it for 2 years (already), I have the tape libraries and tape saturation boost home cdsoundmaster + (coin). Well, it sounds great, but because it eats a lot of resources, I use it less than I would have liked. I have not even tested the libraries of console for sale (home Alexb) who have good reputation, nor the EQ pay because at the workflow concept Nebula is not what is best. To fully exploit Nebula in a mix, it should load several instances by track and it seems difficult and rather headlock to implement.

Nebula is the kind of software that uses the set without too: load a library (1 EQ 2 API 12kz dB for example) and voila, you have sound hardware in your computer. You'd rather a dB at 10kHz? Bah you load another library, and so on. It's like a sampler of effects. But this is not the convolution technology is less static than the convolution and yeah, it sounds great.

The sound is there but my Nebula gets dusty so I'm using it soon. The EQ is an instance of a Nebula Band consoles Nebula is an instance of the input, a forum for the EQ section, one for output, etc..

In the end I think Nebula is to master his tracks or make a Neve EQ or DW Fearn on vocals for example. But given how the plug in I think that we can use it on all its tracks as the libraries would require the console for example.

The price goes up pretty quickly because there are several options in Nebula, and the optional libraries that you can buy more, me I am already close to 250 € for taking just version 3 pro Nebula bookstores + tap, I'll stop there, I understood the concept, it really is a plug that I use sparingly and at the final price / quality ratio I've seen better.

I have thought of EQ, compressors, preamps, tape, consoles, reverbs that sound good for not too expensive, but ultimately the libraries provided with free Nebula is correct without being exceptional and what is the good name of the plug in sound it is the commercial bookstores, and Nebula is a little world where every library editor scratches here and 20 euros for a EQ, then 40 euro for a SSL console and in the end it is used not so much to Because of greed and workflow plug in resources and RAM. on the other hand in sound is clear that this is what is best, with the best plugs from UAD, Waves, etc..

So I do not recommend this plug in unless you're comfortable at budget (starting from 200 to 300 euros to please you) and you might want to bring a touch of prestigious hardware here and there in your mixes, but if you want to put a Neve and API EQ on all tracks of your song, it's doable but it will bounce / freezer most of your tracks, large galley prospects. Basically there are many good quality plugs today and the alternatives are certainly more usable than Nebula.

If you are shielded from money, it is better to take a UAD I think if you have a tight budget, Nebula may be your style but think about it 2 times before you leap.
