Here a direct “forward” from the sursound mailing list, maybe interesting.
The 3D Tune-In Toolkit (a binaural spatialisation tool with hearing loss and hearing aid emulators, freely available as C++ code, as well as standalone app, VST plugin and Unity asset) has changed license, and is now under LGPL. This means that you can actually use the open-source code and incorporate it in compiled software you’ll then commercialise and sell, without needing a specific license from us or pay royalties. If you though modify it, then it needs to be released open-source with the same LGPL license. More information about the 3DTI Toolkit can be found at the end of this email.
It’s though important to underline that the 3DTI Toolkit has been superseded by the Binaural Rendering Toolbox - BRT (GitHub - GrupoDiana/BRTLibrary: The Binaural Rendering Toolbox (BRT) is a set of software libraries, applications, and definitions aimed as a virtual laboratory for psychoacoustic experimentation. The BRT is developed in the framework of the SONICOM project and includes the algorithms developed in the 3D Tune-In Toolkit in a new open, extensible architecture. · GitHub), which incorporates several more functions, tools and versions (as well as the actual 3DTI Toolkit, which is the actual binaural renderer). The BRT is GPLv3, so it can be used for free as long as whatever you release incorporating it is as well released with a GPLv3 license. If you are interested to know more about the BRT, please get in touch and we’ll be happy to share some demonstration and training material.
Of course please share with colleagues and students!

You can find some details about the 3DTI Toolkit spatial audio implementation in this paper:
And the code is available from the GitHub repo:
An example of the functionalities of the Test Application can be found in this video (use headphones when listening):
and here is a video demonstrating the hearing loss/hearing aid functions
The Test Application (the one you see in the videos) is available for MacOS, Windows and Linux at the following link:
At the link above, you can also download the VST plugin, both for MacOS and Windows, as well as the Unity wrapper
