Dear Colleagues,
We have recently released the v2.0 of our Binaural Rendering Toolbox (BRT), an open-source software suite for headphone-based immersive audio applications and psychoacoustics research. The BRT Library integrates and expands upon the foundations established in the 3D Tune-In Toolkit, taking its place from now on (please though note that hearing aid and hearing loss emulations are not yet integrated in the BRT). It is written in C++ and includes several models, modules and tools for binaurally spatialising sound sources, including different reverberation models (convolution-based, SDN, etc.), source directivity options, user-imported HRTFs (real-time swap), BRIR support, near-field simulation, full remote control via OSC, Unity wrapper/asset, user-friendly GUI, and more.
More information, as well as the BRT Library code and the various releases, can be found here:
https://github.com/GrupoDiana/BRTLibrary/
The new online documentation, which includes also a quick start guide, can be found here:
https://grupodiana.github.io/BRT-Documentation/
We will present the various updates and functionalities at the Forum Acusticum 2025 in Malaga (https://www.fa-euronoise2025.org/) in session A24.05. We are also organising an online workshop sometime in Autumn 2025, where we’ll give an overview of both the theoretical basis and technical components of the BRT and of its various releases, and we’ll demonstrate its various functionalities. We’ll then have a follow-up session a few weeks later in order to further support the use of BRT within your team and lab.
The BRT Library will continue to be actively maintained and developed. Among the upcoming features to be incorporated are a hearing loss (HL) and hearing aid (HA) simulator, an ambisonics-based reverb module, and a hybrid reverberation method that simulates early reflections using the image-source method (ISM), and allows flexible integration of other techniques for the late reverberation tail.
If you are interested in attending this, please fill in the following form:
