Updates on the Real-Time Spherical Array Renderer (ReTiSAR)
* Präsentierender Autor
Zusammenfassung:We recently presented ReTiSAR, a framework for binaural rendering of spherical microphone array data in real-time. The array signals and the employed head-related transfer functions are processed in the spherical harmonics domain to compute the resulting ear signals and virtually place a listener into the captured sound field. In this contribution, we present the latest additions to the Python software package. These comprise, among others, an interface to the Spatially Oriented Format for Acoustics (SOFA), the ability of switching between different spherical harmonics rendering orders, as well as performance optimizations enabling real-time rendering up to 12th order. Furthermore, we integrated diverse enhancements recently proposed in the literature for the upper frequency range where spatial aliasing occurs.
