The activity of sound design is setlled at Ircam since the 2000s and has been progressively developed in order to associate this polyvalent artistic discipline with scientific knowledge, methodologies and tools, especially from the auditory perception and cognition field of research. A new step of devlopment is about to come out and globally aims at considering sound design through the prism of design and science of design as defined by Cross: "the study of the principles, practices and procedures of [sound] design" (Cross, 2001) This past, present and future of sound design at Ircam will be presented and deeply illustrated with two fields of application: in research, a presentation of the Skat-VG project dealing with concept and tools of sound sketches with the use of voice and gesture; ii/ in pedagogy, a presentation of the Sound Design Master cursus at ESBA TALM (School of Fine Arts, Le Mans) and especially the workshop methodology that is annually applied with a mixed group of designer / sound designer students and an industrial partner proposing a real use case.
