This work of thesis deals with the musical analysis and modelling of the particular sound events that structure and shape soundscapes. To this end, this work is organized around two complementary approaches: first, it seeks to assess the aesthetic and conceptual implications of acoustic ecology from a poietic perspective. This implies taking into account not only the theoretical principles underlying acoustic ecology, but also a set of criteria characterizing ways of listening from a phenomenological point of view. Secondly, this work introduces a specific dialogical methodology for identifying, describing and modelling the musical functionality of soundscape compositions, while fostering the deployment of other (rather syntactic) compositional techniques.Despite its wide acceptance as a mimetic approach to reconstitute soundscapes through field-recordings, one cannot fail to observe that, over the evolution of the repertoire of soundscape compositions, composers and acoustic designers have developed various compositional strategies and sound-processing methods that enable them to undertake larger and more sophisticated musical outlets, including abstract and virtual types of soundscape compositions. In this context, this work opens up new perspectives on music composition and musicological research: it is centered around the development of acoustical/musical analysis computer tools, as well as of methodologies supporting a dialogical process towards research and creation for better knowing about musical soundscape composition.On that basis, this work intends to contribute with a set of methodological and computational tools that will enable musicologists and composers to classify and represent the heterophonic field that characterizes the soundscape, particularly in the field of musical writing.
