Sonic Tree – algorithmic hexadecaphonic sound installation – vernissage on 12.12.19

algorithmes, images, sons
exposition double de Daniel Maszkowicz et Robert Turner
Forde, du 12.12.19 au 19.12.19

Nous partons de la figure de l’arbre, trace d’une vision commune et d’une expérience primordiale, point de départ de constructions algorithmiques. L’information se crée en décomposant et triant des données; pour mettre en exergue ce procédé nous décomposons et recomposons des sons et des images afin d’obtenir des réalités altérées. Cette exposition est constituée de “l’Arbre Sonore” (DM) – installation hexadécaphonique immersive – et des images de “Pohutukawa” (RT) – accrochage d’abstractions numériques.

Sonic Tree by Daniel Maszkowicz

Sonic Tree is a metallic structure in a room of concrete, contrasting with the organic movements it incarnates. Its virtual neuron cells exchange electric signals, and its metallic cells propagate sound faster than in the air. Just like any tree, it offers a comforting shelter with the sounds of insects and the soft brease in its leaves.

This sound installation features an autonomous audio dedicated programmable processor containing the algorithms for the real-time processing of audio signals. This processor allows controlling sixteen independent channels, each of them driving sixteen small active speakers distributed alongside the branches of the tree. A small piezoelectric contact microphone place at the top of the trunk allows amplifying the sounds produced by the movements of the metallic chains.

An artificial neural network has been implemented with sixteen neurons, each of them corresponding to one audio channel. The signal emitted by each neuron results from a matrix combination which coefficients reflect the sound interactions in the network. The original sound source comes from the contact microphone, and is processed by the neuron network for an effect of an organic movement through the branches of the tree.
