T28 - Creating Immersive Spatial Audio for Cinematic VR
Presenter:Marcin Gorzel, Google Inc. - Dublin, Ireland; YouTube - Mountain View, USA
In this tutorial we will focus on theory and practice for creating immersive spatial audio for cinematic VR experiences. No knowledge of spatial audio is assumed, however experience in audio technology or sound design would be helpful to understand some concepts covered in this talk.
After completing this tutorial, you should have a basic understanding of theory behind spatial audio capture, manipulation, and reproduction as well as practical knowledge that will allow you to create and deploy spatial audio on YouTube. We will cover topics like: what immersive spatial audio is and how it conceptually differs from traditional multichannel stereo audio; what is Ambisonics and the notion of sound field reproduction (theory behind spatial audio); what are spatial audio recording and post-production techniques.
We will also cover some YouTube-specific topics and workflows, including preparing and uploading spatial audio to YouTube, spatial audio formats and open source codecs supported by YouTube. You’ll learn how spatial audio works on YouTube mobile (Android/iOS) and desktop platforms or audio DSP algorithms used by YouTube to render interactive binaural audio. Lastly, we will give some insights into spatial audio loudness and quality considerations as well as propose some good practices for creating spatial audio content.
