Acustica is pleased to introduce TAN compressor based on CORE8 with a classic analog VCA compression. TAN it is a very versatile tool to provide a lot of possibilities to shape the sound with gorgeous graphical user interface.

In TAN you will find the most common compressors parameters like attack, release, threshold, ratio, dry/wet and gain, to allow you an extremely wide range of adjustments, but the exciting news is what we call "ShMod", a compressor shape control for the attack behavior that allows you to fine-tune the attack shape so you can really customize the attack behavior for any audio source.

Preamp Section:
• Hardware preamp simulation (PRE): on and off.

Compressor Section:
• Threshold: from -64 dB to +0 dB.
• Ratio: from 2, 4 and 8.
• Attack: from 0.1 ms to 30 ms.
• Release: from 0.1 sec. to 1.6 sec.
• SHMod (adjustable attack shape): from 0 to 4.
• Gain: from 0 dB to 24 dB.
• Dry/Wet (parallel compressor): from 0 to 100%.

Formats Supported:
• Support operation systems: OS X and Windows.
• Supported plug-in formats: VST2, AAX, and AU.
• Supported architectures: 32 and 64-bits.

Price and Availability:
• free. Available as a digital download immediately after website registration.

About Acqua Effect plug-ins:
An Acqua plug-in is a stand-alone skinned Nebula library, in other words it is a software product developed as a parametrization of one or more Nebula's instances. Parametrization is achieved using the script languages proprietary to Acustica Audio and does not require external tools and compilers.

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 behavior of an audio processor, by reproducing its harmonic response, harmonic distortion and dynamic response as time and other external variables (like user controls) change.

Nice analog compressor, looks and sounds good (very clean and transparent) and also offers simplified parallel compression with its "Dry/Wet" knob. Only has fixed Attack (0.1, 0.3, 1, 3, 10, 30), Release (0.1, 0.2, 0.4, 0.8, 1.6) and Ratio (2/1, 4/1, 8/1) values, so it might not be something for everyone.

It has a small and barely visibile gain reduction meter to the left side, but at least it got one. The plugin is IMHO beside the fact of not being resizable not too big and not too small for modern desktops. I like the horizontal space it occupies on my screen and fits with that maybe in a good spot, where other plugins wouldn't be that good. Especially when you have several GUI of plugins loaded, this could be efficient.

There is also a pre-amp lever on the right side, which to be honest, I can only hear a very subtle difference with which seems to glue the signal more together. I like it but it is very subtle. Maybe it just works belong to knob, but I'll try to find it out in the future. The manual does not say much about.

Speaking about the manual, you can download one at the TAN page in the "Aquarius" installer but it's really made in rough style despite giving you some decent numbers. Probably the roughest manual I've ever seen for a plugin. It's intended to look like that obviously.

Downside is clearly the installation process, which probably is also the reason why this compressor isn't more popular.

You have to create an Acustica Audio account and install the "Aquarius" installer suite from Acustica Audio to get it to your computer. But that's not the only problem. You only can find plugins inside of the "Aquarius" app by a search bar, which works bad. Sometimes it encounters what you want, other times it presents you something else or it just works very laggy.

Acustica Audio itself states at their website regarding the app, "Having a reliable fast internet connection is mandatory." - Another thumbs down from me for that at this point.

Having found the plugin, you can choose whether to install in VST2, VST3 or AAX in 64-bit to a specified location. I wanted the VST2 version (since my Ableton Live 9.7 does not have VST3 support), but interestingly Live couldn't recognise it. So I decided to install the VST3 and bridge it with vst3shell, that did work and so I use the plugin in this way.

Another thing ist that you actually get 2 plugins, TAN and TANZL (which probably stands for TANZeroLatency). I tried TAN it is gives me (52.2 ms, 2459 samples) latency. That is way too much for my use of it. I guess this is also why they created TANZL, with whom I get (2.8 ms, 132 samples) latency, which is fine.

So, if you dare to pass over the stoney path of installing that plugin properly, I highly recommend you to only use the TANZL version.

CPU usage: TAN 5-6%, TANZL 6% (quite much for both in comparison to other competitive plugins)

I won't give it 3 stars, because I actually quite like using TANZL for its clean sound, space and feeling.

Quick Tip:

(My experience is from 03.04.2017) On the download screen, the site says:

Please try with different browsers if you have some issues with the download!

I'm using a MacBook Pro, running OS X 10.10.5 and, in fact, encountered some issues!

Safari would ask for a password then say the page was expired, then ask for box.com account login credentials! FAIL

Chrome made it a step further than Safari, but hung up trying to connect to box.com FAIL

but when all hope was lost...


FIREFOX came through LIKE A BOSS!

I share this story with the hope that it saves someone some time or frustration.

Best of luck with your installations, my friends!
