Deciban is chdh's new audiovisual performance where sound and visual shapes emerge from noise. On the screen, a video noise similar to the "snow" of old analog TVs fills the entire space. This hypnotic material, accompanied by its sound alter ego, is animated and set in motion by forces controlled in real time by two performers using laptops. The noise acquires a structure, a topology, patterns. Shapes emerge, visual and sound movements appear. The public loose themselves in the perception of this world full of illusions. In Deciban, phenomena are drowned in a noise universe: noise is information. Inspired by Claude Shannon's information theory, Deciban is a research on the perception of digital generated noise that aims to propose a new type of synaesthetic experience.

The chdh collective studies images / sound relationships by creating audio and visual algorithmic synthesizers. They mainly use these audiovisual instruments during live performances. Using equations describing natural mechanisms, they generate abstract choreographies of particles whose minimalist matter reveals underlying structures of great complexity, shaped by strange organic attractors. In search of a synaesthetic radicality, their hypnotic performances work on the joint movements between image and sound and belong as much to experimental cinema in the form used as to improvised music in the way they are played. Since the early 2000s, they have shown their projects in more than a hundred international venues, especially the Egregore performance (2011), which explores the group movements of a crowd of particles and Morphist (2015), a study of the shape transitions of an abstract substance. This work has also led to two editions: the Vivarium DVD (Art Kill Art / Arcadi - 2008) which contains abstract video works as well as the software developed for these creations, proposing to "replay" or edit them, and the Egregore - source USB key (Art Kill Art - 2014), an adaptation of the software used for Egregore, which has resulted in a remote performance on more than 120 computers in about twenty countries. Defender of free software, they freely distribute their projects and the tools developed for their work, including the pmpd physical modeling library for Pure Data.
