Real-Time Implementation of Binaural Rendering of High-Order Spherical Microphone Array Signals
Paper in proceedings, 2019

We present ReTiSAR (Real-Time Spherical Array Renderer), an open-source implementation of real-time binaural rendering of signals obtained from spherical microphone arrays. The implementation was performed in Python and bases on the previously published SOFiA toolbox as well as on sound_field_analysis-py. We can confirm that Python together with the other tools employed constitutes a viable framework for this kind of heavy-computation application even under real-time constraints. The current version of ReTiSAR is able to render signals of up to 8th order on a standard laptop computer.
