Abstract : This thesis analyses the notions of real time and differed time such as they are to be found in contemporary music and in computer music. The first part analyses the historical background of this two notions and how related they were with the raising of computer science in the early 60's. Then it develops a critical analysis of the split of real and differed times into two dichotomic categories, based on the coexistence of incompatible definitions of the latency threshold. It then formalises an alternate representation, building up a "latential" axis integrating real and differed times. This representation is finally illustrated by means of three axial analysis, using a program dedicated to relative and subjective sorting. Beside this theorical development, the second part presents five musical collaborations in which I have programed the computer part with Max/MSP. Those five collaborations gave birth to several programs: CBox, on a project about exploration of circularity possibilities, with composer Mario Lorenzo; Mimi and Rose amère, on a project for an augmented viola towards improvisation, with violist Stéphanie Réthoré; FeedItBack and Iviv, mainly on his musical piece Vivo / In Vitro, for augmented snare drum, with composer Santiago Quintáns; a2m, Loterie, Emzed and Nappe, on his musical piece war-sollichwer-den, for clarinet, audience and computer, with composer Mauricio Meza; Plugiscope, Ifso, and Ultraviolette, respectively on a first project for voice, a second one for bass clarinet, and a third one for percussion, with clarinetist and composer Iván Solano. At last, the thesis briefly ponders over the role of the computer music designer.
