A new Inter issue on sound art

The new issue of Inter Art Actuel (98) is devoted to sound art. The texts assembly and the CD create a very nice issue on that matter. You can also read my paper "Au sujet des affects bruyants" in this issue. See http://www.inter-lelieu.org/.

Le numéro d’hiver 2008 d’Inter, art actuel, fruit d’une première collaboration avec l'équipe d'Avatar, a pour objet les « espaces sonores ». L’évolution de la pratique des arts sonores y est cernée et analysée sous différents angles, telles la loi, la technique et la sociologie. Cette livraison donne également à entendre cette évolution, par le biais du disque compact qui y est inclus. D’autre part, la section du Lieu, centre en art actuel présente les travaux de Danny McCarthy, David Neaud et Yves Tremblay. La section « topos » effectue un retour sur La collection de La chambre blanche, Le dispensaire de Folie/Culture, la rencontre Corpolìticas ayant eu lieu Buenos Aires et la Biennale internationale du lin de Portneuf. La section in memoriam rend hommage à Isidore Isou, décédé en juillet dernier.

New classification of spatial sound technologies

My classification of the spatial sound technologies (for reproduction) is now online:
http://www3.sympatico.ca/philippe_aubert_gauthier/spatial_sound.html

More details, explanations and examples are given for each type of technique. This classification was introduced in my Ph.D. thesis, in www.econtact.ca and in the Journal of the Acoustical Society of America.

In this new version, I discuss some points for which I have received critics over the years. I think that the classification survived these critics.

Ph.D. thesis defence of Philippe-Aubert Gauthier

English follows, sorry for cross posting.

=======================================================================

Bonjour,

Vous êtes invité à la soutenance de thèse de doctorat en génie mécanique de Philippe-Aubert Gauthier concernant la synthèse de champs sonores adaptative le 11 septembre 2007 à 9:00 (Université de Sherbrooke, A1-228, Faculté d'éducation). La soutenance se déroulera en français et la période de questions pourra mélanger l'anglais et le français.

La thèse en question concerne la reproduction de champs acoustiques par «wave field synthesis» (WFS) et la compensation des erreurs de reproduction par «adaptive wave field synthesis» (AWFS), soit l'originalité de la thèse. Une part de la présentation sera dédiée aux techniques de spatialisation sonore et une autre concerne les limites de la WFS et des exemples théoriques et pratiques d'AWFS. La présentation touche différentes disciplines : acoustique physique, acoustique des salles, traitement du signal numérique, électroacoustique appliquée, etc. Des efforts sont faits pour conserver une description générale lors de la soutenance et ainsi contribuer à la vulgarisation du travail effectué, la présentation se veut donc ouverte à un public plus large.

Le comité d'évaluation de thèse regroupe Alain Berry, Yann Pasco (Groupe d'Acoustique de l'Université de Sherbrooke, Centre for Interdisciplinary Research in Music, Media and Technology), Oliver Warusfel (IRCAM) and Emmanuel Friot (LMA, Marseille).

La soutenance sera effectuée par vidéoconférence entre Marseille (LMA) et Sherbrooke. La présentation, selon la tradition, doit tenir en 45 minutes. Ensuite, la période de questions peut s'étendre sur une heure ou deux. Lors des questions, la priorité va aux membres du jury. Par la suite, le jury se rencontre et émettra la décision finale quant à l'obtention du doctorat par le candidat Philippe-Aubert Gauthier.

Vers l'heure du diner un apéro (avec quelques bouchées) sera offert au laboratoire du GAUS (C1-2039) où il sera possible de profiter d'une démonstration du système de reproduction de champs sonores.

Hello,

You are invited to the defence of Philippe-Aubert Gauthier for Ph.D. in mechanical engineering on September 11th, 2007, 9:00 (University of Sherbrooke, A1-228, Faculty of education). The thesis concerns the adaptive synthesis of sound fields.

The defence will be presented in French and the period of questions will possibly involve English and French. The thesis relates to the reproduction of sound fields by "wave field synthesis" (WFS) and compensation of the reproduction errors by "adaptive wave field synthesis" (AWFS), that is the originality of the thesis.

A part of the presentation will be dedicated to the techniques of sound spatialization and another part presents the limits of WFS along with theoretical and practical examples of AWFS. The presentation touches various disciplines: physical acoustics, room acoustics, digital signal processing, applied electroacoustics, etc. Efforts will be made to preserve a general description and thus contribute to the popularization of the work. The presentation is thus opened to a larger audience.

The evaluation committee gathers: Alain Berry, Yann Pasco (Group of Acoustics of the University of Sherbrooke, Centre for Interdisciplinary Research in Music, Media and
Technology), Oliver Warusfel (IRCAM) and Emmanuel Friot (LMA, Marseille). The defence will be "videoconferenced" between Marseille (LMA) and Sherbrooke. After the defence, an aperitif (with some food) will be offered in the GAUS laboratory. A demonstration of the system will also be presented in the laboratory (C1-2039).

Pure-Data Convention 2007 :: Montréal :: "Auditory Tactics"

From http://convention.puredata.org/

The PureData Convention '07 will bring together artists, developers and theoreticians who develop, use and reflect on PureData. It will acknowledge the broad range of artistic disciplines that make use of the software and will address questions of openness and accessibility. It will provide a theoretical context for the understanding of media art practices that engage in the aesthetics and politics of Free Open Source Software Culture.

The artists and researchers Philippe Pasquier and Philippe-Aubert Gauthier were invited in 2006 for a residency at Vidéographe to work on the creation of a sound installation for the PD Convention. The residency will start on June 21th until the show opening on August 21th, Concordia University.

"Auditory tactics" (preliminary title) will expose a public space to acoustic beams using compact loudspeaker arrays. PD will be used to control the system, steer the beams and create an interactive spatial sound composition with the public, the space and the system. Using voice sounds, this project is dedicated to the place of the voice, the mediated voice, on public spaces, private and public aural spheres.

See : auditorytactics.blogspot.com

Here is the installation (Concordia University, Québec, Canada) ...

Adaptive wave field synthesis

Next week, my thesis on adaptive wave field synthesis for sound field reproduction will be finished. Here is a picture of my spatial sound system in hemi-anechoic chamber.

Noïzefer CWU and the DSM-V+ by Folie Culture

Between September 10th and 16th, Noïzefer was performing in the street of Québec City (Québec, Canada). This was for an international art and psychiatric event : DSM-V+. The real DSM stands for Diagnostical and Statistical Manual of Mental Disorders. Noïzefer was diagnosticed of "affective bruyante" (noisy inflamation of the affect).

Here are some pictures of the "manoeuvres" in chronological order, as the days pass, the traces left on the street are bigger and bigger. As the days pass, Noïzefer was more noisy: disturbing the diffusely controlled public space.

The first day, the traces were relatively small and we walked few hours ...









On the second day, a rain storm forced the temporary construction of a protection where we realized our sound performance under the rain, under the plastic ...

Noïzefer participation to the Harvest Moon Symposium

On September 21 (2006), Noïzefer (P.-A. Gauthier alone, this time only!) participated in an electroacoustic/acousmatic concert as a a part of the Harvest Moon Symposium 2006 edition (Concordia University, Montréal, Québec, Canada). The short proposed piece was composed for a eight-channel sound system.

Noïzefer CWU: performance for the "Rencontre internationale de performance de Québec" passage in Sherbrooke

On September 24th, T. St-Pierre and P.-A. Gauthier performed at the Horace Art Galery (Sherbrooke, Québec, Canada) as Noïzefer CWU. The performance was "Au sujet de la naissance des affects bruyants". Here are some pictures and description.

Here are some general views of the event ...

The two dark objects are loudspeakers which were projecting the sound track: a progressive accumulation of 25000 sine waves towards pure noise. I was trying to read a text while Tanya was playing a little black piano. Two subwoofers were also adding low frequency drones to the other noise sound tracks.

The visual display, including the costumes, was a creation of T. St-Pierre and the sound track was a composition of P.-A. Gauthier.

The third picture shows some members of the audience, where you can see some of our friends and other performers, you can see Daniel Acosta (Argentina) on the left and Sébastien Pesot (Québec) on the left but in the back.



As you can see on the last picture, one of the central visual element was a red mixture, under a red light, in a plastic bag over a metal pipe. The metal pipe was used as a wave guide connected to one of the subwoofers so that the bag was strongly vibrating: then making noise and giving the mixture a "boiling" look. Few drops of the mixture were constantly emerging from the mix.

Noïzefer CWU was performing live on thursday (October 19th)

Noïzefer was peforming live a new 40 minutes set at the "Home Music Festival" within the art galery "L'Oeil de Poisson" (Québec City, Québec, Canada). Several newspaper articles were published before the event "Home Music Festival", see these references: www.lesoleil.com ("L'art du sous-sol") and Voir.

Welcome

Welcome to this blog :: P.-A. Gauthier, T. St-Pierre, Noïzefer and other things. We (DR TANR, T. St-Pierre and P.-A. Gauthier) hope to publish our more recent activities on this blog. Noïzefer is a peformance and music duo created from a real love story...
