List of Authors

Daniel Arfib (born 1949) received his diploma as “ingénieur ECP” from the Ecole Centrale of Paris in 1971 and is a “docteur-ingénieur” (1977) and “docteur es sciences” (1983) from the Universite of Marseille II. After a few years in education or industry jobs, he has devoted his work to research, integrating the CNRS (national center for scientific research) in 1978 at the Laboratory of Mechanics and Acoustics (LMA) of Marseille (France).

As the chairman of the COST G6 action named “Digital Audio Effects” he has been in the middle of a galaxy of researchers working all around this subject. He also has a strong interest in the gesture and sound relationship, especially concerning the creativity in musical systems.
