This work conjures up a dreamy vision. Two spaces, two constrasting climates. First, at the edge of dawn, a calm and serene horizon, cold and blue. Suddenly this space becomes enclosed, the cold light growing purplish to the point of becoming incandescent. The place fills with wild, excited creatures whose acoustic traces are contrapuntal to the clash between tectonic materials in motion.

Here again, the acousmatic writing proceeds from an esthetics marked by contrasting morphological signatures whose mutations are unpredictable and bring to mind colours, textures, and shapes. The work starts with long, stable, diaphanous stretches of sounds, akin to laments. These are brutally perturbed by cracklings, granulates, and “acoustic arcs” generated by saturation that rips the sound screen apart.

The materials in Les aurores pourpres come from sound synthesis and treated acoustic source recordings. To achieve this result, I had to go back to old sound banks from the early 1990s I had collected in the course of a year of creation and programming at Stanford University (California, USA).

To form the materials of the work, I used an infrared motion sensor that allowed me to control, through the gestures of one hand, up to five audio parameters simultaneously in additive synthesis and modelling synthesis applications. I used the same controller to treat my materials old and new, notably in the software Cecilia. Using this infrared sensor allowed me to imprint a gestural signature, lively and organic, to the morphology and outlook of the sounds, and to let the expressive qualities of the material come through.
