Portrait of Felix Perfler

I work on binaural audio and auditory modelling, building learnable filterbanks and parametric pinna models for HRTF personalisation.

PhD student at the Acoustics Research Institute, Austrian Academy of Sciences.

BS and MS in Audio and Electrical Engineering (University of Music and Performing Arts Graz; Graz University of Technology).
