Joseph Larralde is a programmer in IRCAM’s ISMM team. He’s also a composer / performer using new interfaces to play live electroacoustic music, focusing on the gestural expressiveness of sound synthesis control. His role in the RAPID-MIX project is to develop a collection of prototypes that demonstrate combined uses of all the partners’ technologies, to bring existing machine-learning algorithms to the web, and more broadly to merge IRCAM’s software libraries together with the ones from UPF and Goldsmith in the RAPID-API.
