In this lecture by visiting Regents' Lecturer René Caussé, a digital signal processing method for radiation pattern synthesis is presented. In the first part, typical radiation properties of musical instruments are illustrated and discussed from a perceptual point of view. The second part describes the method of radiation pattern synthesis. The performance is discussed and illustrated by measurements undertaken with different prototypes. The possible applications in the field of music and electroacoustics are discussed.
