Bayle's aesthetic radicalism is based on a conception of a living space in which there is not an opposition of an inner space to an outer space. This idea will be discussed by looking at the morphology creation, temporal evolution and sound spatiality on Francois Bayle's works. Sound events as images-of-sounds' are characterised by a philosophy of dynamic production and energy transformation which creates a space in movement. However, the organisation of time structure in Bayle's works can be divided into three categories (discrete time, time based on independent moments and circular time) corresponding to three periods of his creative life. We can conclude that this organisation led him to realise how important the active behaviour of the listener is for the construction of space. As a result, the spatial experience does not create a constructed space but rather a subjective one in which the listener is a resonant subject with the space surrounding him.
