This paper describes a method dedicated to radiation synthesis. In the first part, some radiation properties of musical instruments are illustrated and discussed on a perceptual point of view. The second part describes a radiation synthesis method which consists in optimizing the combination of the acoustic fields radiated by digitally controlled transducers. The performance of the method is discussed and illustrated by measurements undertaken with different prototypes. The possible applications in the field of music and electroacoustics are stated.
