3D Sound Techniques: Analysis and Synthesis

Imperial College London
Synopsis:
What is 3D sound? How can it be simulated? Why is it relevant to virtual reality and HCI?
The aim of this talk is to overview the most known and used 3D sound technologies and techniques. After a brief explanation of the mechanisms of spatial hearing perception, I will carry out an overview of the techniques for 3D sound recording and analysis. This will start from standard stereo recording, MS (Mid/Side) and binaural, going towards more complex techniques such as Ambisonics and DirAC (Directional Audio Coding).
In the second part of the presentation, I will talk about 3D sound synthesis and reproduction, looking again at techniques such as binaural and Ambisonics, and at other ones such as VBAP (Vector-Based Amplitude Panning) and WFS (WaveField Synthesis).
Biography:
Senior Lecturer in the Dyson School of Design Engineering, and an active researcher in the Industrial Design and Human Factors groups. In the past years I have worked in Italy (Università degli Studi di Milano), France (LIMSI-CNRS and IRCAM) and UK (De Montfort University) on projects related with 3D binaural sound rendering, interactive applications for the blind, audiology and audiometric techniques, hearing aids technology, audio and haptic interaction and, more in general, acoustical virtual and augmented reality.
I am the Director of Undergraduate Studies within the Dyson School of Design Engineering, and the scientific coordinator of the EU-H2020 3D-Tune-In research project.
