Désintégrations, for 17 musical instruments and computer generated tape (1982–83) is a musical composition by Tristan Murail, commissioned for IRCAM, Paris. "Although the tape does not attempt to 'simulate' any particular instrument, an organic unity between it and the orchestra is established such that the two blend perfectly. The title refers to this process of voyaging inside sounds and exploring their inner life; sounds melt before us, allowing us to discover their interior."
According to Curtis Roads, "Three compositions produced in the 1980s stand as good examples of compositional manipulation of analysis data: Mortuos Plango, Vivos Voco (1981) by Jonathan Harvey, Désintegrations (1983, Salabert Trajectoires) by Tristan Murail, and Digital Moonscapes (1985, CBS/Sony) by Wendy Carlos." "This piece is more discontinuous than Gondwana and it includes some dramatic silences, particularly in the 6th section."
It has been recorded by the Ensemble l'Itinéraire.
