Data-driven optimization of parameterized head related impulse responses for the implementation in a real-time virtual acoustic rendering framework
Fenja Schwark1, Stephan D. Ewert1, Marc René Schädler1, Volker Hohmann1,2, Giso Grimm1,21Medizinische Physik, Universität Oldenburg, and Cluster of Excellence “Hearing4all”, Oldenburg, Germany2HörTech gGmbH, Oldenburg, Germany In real-time virtual acoustic rendering, the head related directional properties of the receiver, i.e., the listener, are often modeled by convolving the signal with measured head related impulse responses (HRIRs). …
