// The Ambisonic Toolkit (ATK) is intended to bring together a number of tools and
// methods for working with Ambisonic surround sound. The intention is for the toolset
// to be both ergonomic and comprehensive, providing both classic and novel algorithms
// to creatively manipulate and synthesise complex Ambisonic soundfields.
//
// The tools are framed for the user to think in terms of the soundfield kernel. By
// this, it is meant the ATK addresses the holistic problem of creatively controlling a
// complete soundfield, allowing and encouraging the composer to think beyond the placement
// of sounds in a sound-space and instead attend to the impression and image of a soundfield.
// This approach takes advantage of the model the Ambisonic technology presents, and is
// viewed to be the idiomatic mode for working with the Ambisonic technique.
//
//
// We hope you enjoy the ATK!
