Sound Installation

2015

P.-A. Gauthier & T. St-Pierre

“The number of permutations for n=6 possible choices, selected r=2 at a time.” Through this miniature sound installation, Gauthier and St-Pierre revisit the idea and culture of the individual listening station. In fact, they expose listeners to approximately 10 Gigabytes of compositions and improvised sounds, totalling 20 hours of material improvised in tandem via different, more or less mastered, electronic and digital devices. At CLARK, audience members can listen individually or in groups by combining audio tracks played on six separate earphones. In this project, the act of listening, the aesthetics of listening through the accumulation of sound particles, and combinatorics are substitutes for the act of composition.

P(n,r) = n!/(n-r)!

Projet sonore conçu pour le Poste Audio du Centre Clark à Montréal - septembre 2015.

 

« Le nombre de permutations pour n=6 choix possibles et sélectionnés r=2 à la fois ». Avec cette installation sonore miniature qui revisite l'idée et la culture du poste d'écoute individuel, nous exposons les auditeurs et glaneurs à pas loin de 10 Gigaoctets de compositions et d'improvisations sonores. Pour un total d'environ 20 heures de matériel improvisé en duo via différents dispositifs électroniques et numériques plus ou moins maîtrisés. Écoute individuelle, écoute de groupe, combinaison des oreillettes. L'auditeur visite, recompose et spatialise notre disque dur. L'acte d'écoute, l'écoute esthétique, le pointillisme et la combinatoire se substituent au travail de composition.

 

Intentions artistiques

 

Pour ce projet, nous travaillons sur l'idée de poste audio comme tel, c'est-à-dire le poste audio comme sujet. Ce projet s'inscrit donc dans la lignée des principaux sujets reliés à la démarche de Philippe-Aubert Gauthier, soit le sujet de l'espace et de la spatialisation/fragmentation du son en télécommunication [1], combiné à la pratique du collage de Tanya St-Pierre. L'idée de départ est de créer un poste-audio-installation, mais à échelle individuelle. Notre intention est de confondre le contenu audio avec l'objet même du poste.

 

Le résultat attendu est grandement influencé par notre propre façon de travailler les arts sonores, et parfois même la musique. Cette manière est une méthode plus proche de celle de l'auditeur que de celle du compositeur, un peu comme le précise Kim-Cohen au sujet des pratiques arts sonores en général [2]. Ainsi, puisque nous agissons plus comme des auditeurs que comme des compositeurs, nous voulons partager cette idée fondamentale avec les visiteurs et auditeurs du poste audio qui pourront écouter, explorer et combiner à leur guise leur propre agencement via une recomposition, voire permutation, binaurale et individuelle des matières premières. Par exemple, avec six oreillettes et deux oreilles, on trouve P(6,2) = 6!/(6-2)! = 30 agencements possibles. Et ainsi de suite si on combine plus d'oreillettes.

 

Description physique : les sonorités visées et assemblage

 

Dans la lignée de ce que nous faisons actuellement en improvisation avec des circuits analogiques et numériques : les sons comme tels sont constitués de matière plutôt brute sans référence au monde acoustique qui nous entoure, mais ils sont teintés par le contexte d'une approche d'assemblage de style « pointillisme » (tel que défini en musique [3], c'est-à-dire un peu éparse). Pour ce faire, des plages de silence ou de matière de niveau très faible sont intégrées à notre version du poste audio. À l'heure actuelle, nous pourrions définir ce projet comme un genre de poste de ré-assemblage de ce que nous produisons en improvisation libre. Et ce, sans début, sans fin, sans boucle, uniquement des clips brefs avec des listes de lecture aléatoires automatiques. Le but étant d'atteindre un maximum de variations avec une quantité fixe de matières premières, ce qui, évidemment, est aussi teinté d'une claire influence des pratiques combinatoires et procédurales.

 

Description physique : le dispositif

 

En pratique, nous fournissons trois lecteurs médias autonomes programmés (des « Raspberry Pi ») avec amplificateur casque. Ces lecteurs sont accompagnés d'écouteurs modifiés : des écouteurs à une seule oreille, de telle sorte que l'espace alloué est couvert de 6 oreillettes. L'intérêt pour ce genre de dispositif réside essentiellement dans la possibilité d'effectuer de la composition spatiale individuelle ou collective lors de l'écoute.
