Ambisonics & the ATK @ DXARTS

J. Anderson (2016): Ambisonics & the ATK @ DXARTS. Presented at the Pacific Northwest AES Section Meeting (Nov 2017), Seattle.
Originally developed and commercialized as a practical "full 3D" sound recording and reproduction technique in the 1970s, with recent advancements in VR applications Ambisonics is enjoying a renewed interest. Offering both theoretical and functional tool-chains, Ambisonics is ideally suited as an adaptable and "future proof" solution for 3D audio. In this discussion we'll introduce the principal concepts of the Ambisonic technique and review how these are addressed by the tools found in the Ambisonic Toolkit (ATK) software package. Additionally, we'll also offer demonstrations of practical projects created at the Center for Digital Arts and Experimental Media (DXARTS) leveraging the soundfield synthesis and signal processing techniques the ATK offers.
