No matter how powerful and versatile they might be, when it comes to spatial audio, traditional sequencers or DAWs (digital audio workstations) often fail to meet the creative artist's needs. Neither the signal flow architecture nor the user interface is adequately specialized for technologies such as Ambisonics or wave-field synthesis. Choreographer is a step towards a appropriate authoring tool for spatial audio.

The GUI of this software provides different editors to monitor and manipulate virtual positions of sound sources and shapes of trajectories. Each one exposes the spatial data in its particular way, thus supporting different approaches and methodologies: The data can be edited either graphically or numerically in the respective user interface, depending on the situation or the user's individual preferences.

The audio rendering engine which is integrated in this software, is designed for sound spatialisation in Ambisonics and implements Ambisonics Equivalent Panning, a technique conceived at the ICST.

This program's frontend and audio rendering engine are strictly separated, self-contained units. That allows to use them independently, i.e. to author a spatial audio scene to be rendered with a different audio engine or to play back a piece of music that has been created with another composition tool. The intended format for that transmission of meta data for spatial audio is SpatDIF (spatial sound description interchange format). This new standard is currently being developed by a international research team.
