Abstract:
The CEDRIC and the IRCAM conduct since 2002 a project entitled "distributed orchestra" which proposes to coordinate on a network the actors of a musical orchestra (musicians, sound engineer, listeners) in order to produce a live concert. At each site (musician), mainly two components are active: the sound engine (FTS) and an
auto-synchronisation module (nJam), two modules which must treat audio streams in real time and exchange them via the network. These components were first made to run under the Linux environment, where the available schedulers are imposed. For this purpose, we choose to use Bossa, a platform grafted on the Linux kernel in order to integrate new real-time schedulers.
