[ISEA2023] Paper: Christophe Lengelé & Philippe-Aubert Gauthier — Live 4 Life: A dream for a free and open spatial performance tool towards symbiosis or death?

Abstract

Full Paper. Theme Interactive – Networked – Human Computer Interaction Sub theme Symbiotic Individuations

The paper presents the motivations, evolution, and directions behind the spatial sound performance tool named Live 4 Life. It aims to simplify the creation and control in real time of masses of spatialised sound objects on various kinds of loudspeaker configurations (stereo and particularly quadriphonic or octophonic setups, as well as domes of 16, 24 or 32 loudspeakers). This spatial research, which questions ways of associating rhythmic and spatial parameters, is based on the concept of free and open works, both from the point of view of form (improvisation) and in the diffusion of the code. The tool, which was initiated in 2011 and distributed in open source in 2022, has been conceived as a long-term dream against capitalism and loneliness. Several scenarios between (technical, social) death or symbiosis of this tool (with other programs, works and the visual representation field) are presented.

  • Christophe Lengelé (CA) is a spatial sound designer and performer for electronic and experimental music. He particularly focusses on the development of live experimental audio tools and interfaces built from open source softwares like SuperCollider. After studying law and economics and working as a marketing and market analyst in international companies for a few years, he decided to quit the business field in 2006 to study electroacoustic composition. He trained and worked from 2008 to 2012 at the Municipal Conservatory Georges Bizet of the 20th district of Paris and obtained a Master of Arts in computer music at Université Paris-Est Marne-la-Vallée in 2014 and a Doctorate in music (composition and sound design) at Université de Montréal in 2022. He is currently doing a postdoctoral research/creation in spatial improvisation at Université du Québec À Montréal. He seeks to bring together the spheres of composition and improvisation and focus on performing variable spatio-temporal pieces with a global custom live tool. He has been regularly developing this tool since 2011, in order to “play the place and the music at the same time”. His spatial research, which questions ways of associating rhythmic and spatial parameters, is based on the concept of free and open works, both from the point of view of form and in the diffusion of open source code. His works have been presented and performed internationally, particularly at the International Computer Music Conference (2018 and 2021), during the Journées d’Informatique Musicale in France (2017 and 2019), as well as at Akousma Festival 2021 (Montréal, Canada) and more recently at Cube Fest 2022 (Virginia Tech, Blacksburg, USA). He is the recipient of several research-creation grants.
  • Philippe-Aubert Gauthier (CA) received a B.Ing. degree in 2000 and a M.Sc. degree in active control of vibration in 2003 (Université Laval, Canada). From 2003, Gauthier was enrolled at Université de Sherbrooke (Canada) from which he received a Ph.D. degree in 2007, dedicated to adaptive wave field synthesis. He is interested in spatial sound, multichannel sound reproduction, audio signal processing, room acoustics, loudspeaker and microphone arrays, spatial hearing and psychoacoustics. He was adjoint professor at the Mechanical Engineering Department from 2017 to 2019. He then took up a professorship at the Ecole des arts visuels et médiatiques at UQÀM (Canada) in 2019. He is a professional sound artist, an electronic musician, working at the intersection of arts, sciences and technologies. He is currently the associate director of artistic research at CIRMMT (Centre for Interdisciplinary Research in Music, Media, and Technology).
