This video introduces Ambisonics, a family of techniques for rendering and manipulating immersive, spatial sound in three dimensions. These techniques are made possible by the Ambisonic Toolkit (ATK), distributed as a SuperCollider Quark, the development of which is led by Joseph Anderson, a composer and research scientist in the DXARTS program at the University of Washington. Special thanks to Jo, without whom this tutorial would not have been possible, and thanks to the entire team of artists and researchers who've contributed to this fantastic project.
