Jost Muxfeldt uses Audio Kinematics to create virtual audio sculptures, utilizing the spatial relations and proportions of a mechanical structure to determine various parameters of a sound composition.

The motion in the current realization is based on the principle of a mobile, a binary tree structure combined with circular motions. Since the motions of the individual nodes are always circular, they can over time be described with a series of sine waves added to each other. The motion of one node is thus described by the amplitude modulation of the sine wave of the parent node. Thus the motion is closely related to one of the most basic principles of audio synthesis.

The entire structure allows for a total sound experience in which the progression over time is determined on the one hand by the choice of the actual sound components, and on the other hand by the distance and motion of these components in relation to the listener. The listener becomes the center of an sound environment whose shape and timbre changes over time by means of its specific spatial mechanics. The motion is simultaneously projected on a screen so that the listener can follow the mechanics of the sound visually as well. [via]
