Résumé : The use of spatial room impulse responses (SRIR) for the reproduction of three-dimensional reverberation effects through multi-channel convolution in immersive surround-sound loudspeaker systems has reached widespread use, thanks in part to the commercial availability of spherical microphone arrays. This has subsequently created a demand for analysis and treatment techniques not only capable of ensuring the faithful reproduction of the measured reverberation effect, but that could also be used to control various modifications of the SRIR in a more creative approach such as in the production of immersive musical performances and installations. The principal objective of the current thesis is the definition of a complete space-time-frequency framework for the analysis, treatment, and manipulation of SRIRs. The analysis tools should subsequently enable the treatment of measurements with respect to their inherent limitations, and offer the ability to modify the final reverberation effect.
