| Résumé |
Audio networking François Déchelle, Patrice Tisserand, Simon Schampijer (IRCAM, Paris, France) We will talk about distributed architectures for audio and music, focusing on real time audio streaming over Internet and grid computing. Distant musical interaction via Internet has been tackled by numerous project. The 'Distributed virtual concert' project, which aims to provide musicians (electronic or acoustic) a way to play together via Internet, is a collaboration between IRCAM and CEDRIC, the computer science research lab of CNAM/Paris, and is currently implemented as a jMax package. The musicians are connected by audio streams other RTP and a distributed algorithm resynchronize the different streams to a common tempo. The different issues associated with real time audio streaming on Internet will be presented, together with the free softwares available. We will also present some experimentations done at IRCAM on grid computing. Grid computing covers a number of technologies that aim to provide to end users standardized access to processing power and storage using high speed networks. We'll make an overview of current grid computing technologies and describe the free software that are available today on GNU/Linux to build grids and to distribute computations other a network of desktop machines. We will then discuss how grids could be used for musical and audio applications and what they can bring to musicians and audio engineers. |
