---------------------------------------------------------------------
The Ambisonic Toolkit (ATK) is a soundfield kernel support library.
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!
