The 3D Tune-In Toolkit VST Binaural Audio Plugin

This demo paper aims at introducing a novel VST binaural audio plugin based on the 3D Tune-In (3DTI) Toolkit, a multiplatform open-source C++ library which includes several functionalities for headphone-based sound spatialisation, together with generalised hearing aid and hearing loss simulators. The VST plugin integrates all the binaural spatialisation functionalities of the 3DTI Toolkit for one single audio source. The spatialisation is based on direct convolution with any user-imported Head Related Transfer Function (HRTF) set. Interaural Time Differences (ITDs) are customised in real-time according to the listener’s head circumference. Binaural reverberation is performed using a virtual-loudspeakers Ambisonic approach and convolution with user-imported Binaural Room Impulse Responses (BRIRs). Additional processes for near- and far-field sound sources simulations are also included.
