[AUDITORY] Updates about 3D Tune-In Toolkit license and BRT ("Picinali, Lorenzo" )

Subject: [AUDITORY] Updates about 3D Tune-In Toolkit license and BRT From: "Picinali, Lorenzo" <l.picinali@xxxxxxxx> Date: Thu, 5 Mar 2026 08:00:00 +0000 --_000_LOVP265MB8837B63C613EB639FA8ADEDFBA7CALOVP265MB8837GBRP_ Content-Type: text/plain; charset="Windows-1252" Content-Transfer-Encoding: quoted-printable Dear Colleagues, You might (or might not) have used some of our Spatial Audio rendering tool= s before. This is a brief update on two of them. The 3D Tune-In Toolkit (a binaural spatialisation tool with hearing loss an= d hearing aid emulators, freely available as C++ code, as well as standalon= e app, VST plugin and Unity asset) has changed license, and is now under LG= PL. This means that you can actually use the open-source code and incorpora= te it in compiled software you=92ll then commercialise and sell, without ne= eding 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=92s though important to underline that the 3DTI Toolkit has been superse= ded by the Binaural Rendering Toolbox - BRT (https://github.com/GrupoDiana/= BRTLibrary/), 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 rel= ease 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=92ll be h= appy to share some demonstration and training material. Of course please share with colleagues and students!
