Virtual Acoustic & Augmented Experiences

Workshops & Masterclasses (AM - GROUP #1)

The technologies enabling the interpenetration of physical and virtual spaces for an enriched experience of the world present opportunities defying imagination. Be it for the capacity to virtually reproduce the acoustics of physical spaces or to superimpose layers of virtual information on physical spaces, world builders have the means today to explode the limits of experience.

A variety of sensory immersive installations and devices ranging from domes to head mounted displays and orientation tracking headphones will be presented in the context of these workshops.

Workshops list :

RECREATING ACOUSTICS IN REAL AND VIRTUAL SPACES
The space where a sound is produced has a strong effect on the final sound heard by the listener. As a result, a more immersive audio experience can be created by realistically simulating how sound propagates in an environment. This workshop will discuss the most important characteristics of sound propagation and spatial audio, as well as how these effects can be computed efficiently for interactive games and VR. An interactive demo of a state-of-the-art acoustic simulation system will be given. Finally, the presentation will consider the challenges in extending this work to real physical spaces for augmented reality and show a preliminary approach for audio/visual capture of the acoustics of real environments. The objective is to understand the immersive impact of simulating accurate acoustics in virtual- and augmented-reality spaces.

MULTICHANNEL PHYSICAL MODELLING SOUND SYNTHESIS
In this workshop, the focus is on new directions in physical modelling synthesis, with a particular emphasis on multichannel sound synthesis for musical works. Many systems will be discussed: standard members of the acoustic musical instrument families, including brass, the guitar and percussion, rendering in 3D and room acoustics auralisations, as well as modular physical modelling synthesis environments. Along with many audio examples and graphical visualisations, there will be performances of two multichannel works, entirely synthetic.

SCULPTING AUDIO SPACE : INTERPOLATING NEAR-FIELD / FAR-FIELD AND OTHER RECENT EXPERIMENTS
This workshop will focus on new techniques explored in combining near field and far field spatial audio. Clips and examples will demonstrate the potential of near field trans-aural beam-forming, which was recently deployed in a new “4D holographic theatre” experience in Santa Clara California. Other techniques from the Spatial Audio Lab (Spatlab) at UCSD will be discussed and demonstrated. Participants will be familiarized with new techniques and applications as indicated above, as well as new binauralization techniques developed for Google Spotlight Stories.

SPATIAL ILLUSION INDUCED BY SPINNING SOUND
Our demonstrations are based on research on the spatial perception of sound trajectories. These psychoacoustic studies are inspired by spatialization techniques used in electronic or mixed music. By moving sound sources around at a very high speed, we have observed unseen before spatial phenomena, such as pitch shift illusions induced by acceleration, ambiguities between the speed of movement and characteristics of spatialized sound and sound beats.

SOLUTIONS FOR VR EXPERIENCES
A host of VR/AR head mounted displays with 3D sound and controllers takes the experience of immersion to new dimensions. This hands-on workshop will trace their history, map the emerging solutions and evaluate them in terms of the immersive experience they provide. Featured systems : HTC Vive, Oculus Rift, Samsung Gear VR, Google’s Cardboard and more as they become available.

SPATIAL AUDIO FOR INTERACTIVE MEDIA

This workshop will address the challenges of designing interactive audio for a vast variety of media and rendering setups. Starting with a basic overview on what constitutes interactive audio, we will move on to examine the reality of large-scale interactive audio productions such as videogames. The presentation will explore the tools at a designer’s disposal to plan and organize their projects seamlessly from headphones for VR to ad hoc speaker arrays such as domes, arcades, or museum installations.

Finally, from a spatial audio perspective, we will take the opportunity of running Wwise in the dome and showcase a few experiments related to spatial transformations of ambisonics; reverberation; and the differences between VBAP and ambisonic panning.
