Celestial Psychoacoustic Mastering VST Is FREE Until February 14th!


Acustica Audio has announced that it’s offering the Celestial psychoacoustic mixing tool as a free download until February 14th, 2020.

Celestial is a two-plugin audio mixing suite. It consists of a Texture Mix Processor and a Psychoacoustic Bus Processor plugin. It seems that the plugin is loosely based on the Fusion stereo outboard processor by Solid State Logic. The software is compatible with all VST, VST3, AU, and AAX plugin hosts on PC and Mac.

Intended for use as a specialized mixing and mastering tool, Celestial can deliver a layer of analog texture and warmth to individual tracks or the master bus. The interface is organized into five main sections, with separate controls for the preamp, the two-band equalizer, high-pass and low-pass filters, compressor, and the stereo image processor. The plugin also features input and output gain controls with gain reduction and peak-volume metering. Both the Texture Mix Processor and the Psychoacoustic Bus Processor have identical-looking GUIs.

Check out the official demo video below to see and hear Celestial in action. According to Acustica Audio, they realized that the plugin sounded better than some of their commercial products, but they’re still giving it away as a Christmas gift. It is undoubtedly the type of mastering plugin that can do wonders in the right hands. The only drawback is that, like most software from Acustica Audio, you will need a reasonably powerful machine to run it without performance hiccups. Most users will probably be limited to running a single instance of Celestial in their digital audio workstation.

Celestial is free to download only until February 14th, 2020. You will need to install the Aquarius software from Acustica Audio to download and activate your free copy of the plugin. Acustica Audio is also running a Christmas sale from December 18th until January 7th. Get a 50% OFF deal on Aqua plugins and up to 35% OFF third-party libraries for N4.

  1. Hi, great freebie. There are 4 vsts of this plugin. Two with in L attached to the name. Are thos lite versions of the plugin? The manual is no big help here.

  2. “The instance without audio buffers, or “ZL”, or zero latency, do not have any audio buffer pre-loaded, and will process the audio without any delay, so at the same time CPU load will be higher compared with standard non ZL instance.”

    And I guess MB = master bus and MX = (general) mix !?

  3. Hi guys
    I have a problem with acustica stuff When the celestial install is complete I open reaper and this message show up on my screen
    Plugin celestial.dll excuted invalid operation during scanning.

  4. I have other issues. First it clutters up the plugin folder with lots of unnecessary files. Well if you design it right.
    And secondly EVERYTHING IS IN BLOODY CAPITAL LETTERS. Unnecessary, unimpressed and uninstalled the lot !

    • Amen to that!
      I’m not so desperate for any of these “free” plugins that I’ll blindly clutter my computer with other garbage just to use them.

      One of these “offerings” even had a 32 page installation and authorization manual?!?! Madness.
      I can’t believe folks actually put down money to jump through hoops for the paid stuff.
