David Poirier-Quinot has released Anaglyph, a high-quality freeware (for non-commercial use) binaural spatialization effect in VST plugin format for digital audio workstations on PC and Mac.
The developer shared the Anaglyph concept with the public a while ago (the demo video featured below was published back in 2016), but the actual plugin wasn’t available for download until recently. This still isn’t an official stable release, as the current version of the plugin is 0.9.2 beta. Still, the currently available beta version performed very well during our test, without any noticeable stability issues.

I am by no means an expert in this field so your best bet for understanding the concepts and the science behind the plugin would be to read the documentation provided on the product page. In short, this freeware tool will allow you to simulate the three-dimensional positioning of audio sources in your mix using some of the most advanced techniques that are currently available.
The user interface may seem a bit busy at first, but the most important control parameters are easy to identify and operate. The XY pad on the left controls the basic positioning of the audio source, whereas additional tweaks such as height and zoom are performed using the vertical sliders on the left and right. Unfortunately, a detailed reference manual isn’t available at the moment. You can check out the demo video below for some further insight regarding the plugin’s control scheme.

The current release is compatible with all 64-bit VST plugin host on PC and Mac (32-bit digital audio workstations aren’t supported on PC right now). A Linux version of the plugin is currently in the works and should be released soon. The plugin is released as freeware for non-commercial use. The developer suggests that users should contact them to discuss the licensing terms for potential commercial use. A big thank you goes out to our reader James who wrote in to let us know about Anaglyph.
Anaglyph is available for free download via David Poirier-Quinot’s website (25.5 MB download size, ZIP archive, 32-bit & 64-bit VST plugin format for Windows, macOS, Linux).
