Choreographer is a sequencer / composition environment for spatial music. It is aimed at composers or sound artists as a flexible and intuitive tool for 3D sound source placement.

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. The intended format for the storage and transmission of all spatial data is SpatDIF (spatial sound description interchange format), a new standard currently being developed by a international research team.
