Biography of Joseph G. Tylka

Joseph (Joe) G. Tylka is an Assistant in Research at the 3D Audio and Applied Acoustics (3D3A) Laboratory and a graduate student in the Department of Mechanical and Aerospace Engineering at Princeton University. He received his B.S. in physics from the University of Maryland, College Park, where he graduated cum laude with a minor in philosophy in May 2012. He subsequently received his M.A. in mechanical and aerospace engineering from Princeton University with a concentration in acoustics and signal processing in September 2014. Joe has been a musician for almost his whole life and has had an interest in music technology and audio engineering for many years. He is currently pursuing his Ph.D. and conducting his dissertation research on navigation and binaural rendering of recorded 3D soundfields. His research interests include 3D audio, psychoacoustics, and audio signal processing.

  1. Navigation of Higher-Order Ambisonics Recordings
  2. Conducted objective comparisons of three techniques for soundfield navigation. Developed a method for soundfield interpolation within an array of two or more ambisonics microphones.

  3. Binaural Rendering of Recorded 3D Soundfields
  4. Developing tools and techniques to generate individualized binaural renderings of recorded 3D soundfields.

  5. Loudspeaker Directivity: An Ongoing Experimental Survey
  6. Developed the data processing algorithms used to generate loudspeaker directivity data. Assembled the database of loudspeaker polar radiation measurements. Proposed metrics for directivity and constant-directivity by which the directivities of different loudspeakers may be compared.

  7. Log-Symmetric Fractional-Octave Smoothing
  8. Developed a modified fractional-octave smoothing method that, for spectra that are originally symmetric in log-frequency, preserves said symmetry after smoothing.

  9. Low-Noise Impulse Response Measurements
  10. Proposed an iterative measurement procedure to obtain impulse responses with reduced noise contamination and limited processing artifacts. Demonstrated experimentally that the procedure achieves superior results compared to conventional techniques in terms of measured SNR and peak pre-response amplitude.
