In the field of electroacoustic composition it is very common to simulate spatial movements of sounds. However, some intrinsic features of sound objects, such as their dynamic evolution, are rarely taken into account in this process. This work proposes techniques for the spatialization of a sound object (or a sequence of sound objects) which consist in the conversion of parameters of dynamic evolution into specific spatial trajectories with particular speeds. The description of such trajectories makes possible the matching of ampitude peaks with the position of real sound sources in a multichannel system, thus avoiding the loss or the alteration of gestures cointaned in sound objects.
