Sounds in Space – Audio for Virtual Reality Animations

I’ve had a few people ask for me to share the animations from my Surround Audio for VR presentation that I delivered at Sounds in Space this year.  I’ve made a video of the powerpoint (30 seconds per slide) so everything can be viewed in context (note there’s no audio, though!).  If you weren’t at the event, it goes through both the graphics and audio processing needed to create VR content and shows the limitations, with respect to the inter-aural level (ILD) and time (ITD) differences reproduced by the Ambisonics to Binaural process at varying orders.  8th order Ambisonics does a great job reproducing both the ILD and ITD up to 4kHz.

  1. Nice one Bruce, those animations are great and really revealing in lots of ways. 8th order it is so! 🙂

  2. Thanks, Enda. I chose 4kHz a bit arbitrarily, but 8th order is great up to there. I plan to do more on this after the summer 🙂 The interesting bit, for me is how 1st order is just plain frequency independent amplitude panning (but with a non-flat frequency response) above 700 Hz.
