Anaglyph
Anaglyph is a high-definition binaural spatialization engine that includes a personalizable morphological ITD model, near-field ILD corrections and HRTF parallax selection, a localisation enhancer, an externalisation booster, and multiple HRTF support via the SOFA file format. Its HRTF personalisation lets a listener select their own HRIR/SOFA file and tailor a head-size parameter to optimise lateral localisation cues, while its near-field enhancements specifically improve the sensation of distance for sources placed close to the listener. Developed within an ongoing academic research effort into binaural rendering, it was designed both to support that continuing research and to make its results directly usable for audio engineers inside conventional DAW environments, and it was released as freeware for non-commercial use across Windows, macOS and Linux.

history
+–
Anaglyph was developed by David Poirier-Quinot and Brian F.G. Katz, growing out of research at LAM-CNRS, later IJLRA, at Sorbonne Université, with participation from the Dyson School of Design Engineering at Imperial College London as part of the 3D Tune-In project. The concept was first shared publicly around 2016, before the plugin itself, integrating over a decade of accumulated spatial hearing research, was formally introduced as a beta VST at the AES Convention in Milan in May 2018, alongside an accompanying engineering brief detailing its architecture. Interest grew quickly following coverage from outlets including Rekkerd, Bedroom Producers Blog and Synthtopia, passing 2,300 downloads within months, and an updated version, 0.9.2c, followed that October adding FL Studio support and fixes to its binaural convolution, with further plans at the time for Pro Tools and Audio Unit support and CPU optimisation. The project remained in active development between 2016 and 2020.
