Workshop 5 - Head-Tracked Binaural Audio with BELA


Rebecca Stewart and Rishi Shukla


Immersive technologies with binaural audio are commonly seen as virtual reality headsets for applications such as gaming or 3D film. However, audio-led augmented reality applications where the view of the wearer is not obscured by a headset have been under-explored. This is partially because of the hardware and software requirements for rendering binaural audio in a wearable device. In this workshop we present an open source, wearable system for rendering interactive, head-tracked binaural audio scenes. 

This workshop is a hands-on session in which participants will learn how to use the embedded Linux platform Bela ( to render head-tracked binaural signals. Bela is designed for ultra-low latency audio signal processing, making it an ideal platform for head-tracked audio. Using a combination of Pure Data and C++, participants will be shown how to use an open source library implementing a virtual loudspeaker approach along with how to work with an inertial measurement unit (IMU).


This session includes coffee break.
