The Virtual Acoustic Spaces Unity Spatializer with custom head tracker

The virtual acoustic spaces (VAS) unity spatializer is a plugin for dynamic binaural synthesis for Unity. It can handle impulse responses (IRs) of arbitrary length (limited only by hardware resources). Hence, it is possible to calculate the binaural synthesis not only with head related transfer functions (HRTFs), but also on the basis of binaural room impulse responses (BRIRs). The plugin can also virtualize reflections calculated by raytracing and it is possible to load an individual IR set for each instance. In addition to being compatible with off-the-shelf cross reality (XR) hardware it features a Bluetooth binding for an easily built, custom-made head tracker based on an ESP32 board. It is therefore predestined for audio augmented reality applications.
