%X In this presentation we exemplify the emergence of new possibilities in sound analysis and synthesis with three novel developments that have been done in the Analysis/Synthesis team at IRCAM. These examples address three main activities in our domain, and have reached a large public making or simply listening to music. The first example concerns synthesis using physical models. We have determined the behavior of a class of models, in terms of stability, oscillation, periodicity, and finally chaos, leading to a better control of these models in truly innovative musical applications. The second example concerns additive synthesis essentially based on the analysis of natural sounds. We have developed a new additive method based on spectral envelopes and inverse Fast Fourier Transform, which we name FFT-1 and which provides a solution to the different difficulties of the classical method. Commercial applications are announced for this year, for professional users and soon for a larger public. The last example is an original work on the recreation of a castrato voice by the means of sound analysis, processing andsynthesis. It has been done for the soundtrack for a film and a CD about Farinelli, the famous castrato of the eighteenth century. The CD and the film have reached millions of people all around the world.
