Radiation of Musical Instruments and Improvement of the Sound Diffusion Techniques for Synthesized, Recorded or Amplified Sounds (Revisited)

cote interne IRCAM: Causse95a/National audienceThis project is articulated around three principal research axes: a) the collection of radiation data of musical instruments from measurements or from the simulation of their physical functioning; b) development of signal processing methods in order to control the directivity of an array of loudspeakers; c) evaluation of the perceptual cues linked with the variation of the radiation characteristics. In this paper we review some of the developments of this project and new results obtained during the last three years (Caussé et al., ISMA, 1992; http://mediatheque.ircam.fr/articles/textes/Causse92/
