Amplitude Modification Algorithms within the Framework of Physical Modeling and of Haptic Gestural Interaction
Résumé
Every underlying technique that has been used for the realization of audio effects since the beginning of electronic and computer music, introduced different types of sound modifications and proposed new ways of control. The advent of digital signal processing has stimulated the audio processing researchers to a great extent; thus a variety of algorithms were designed to provide novel sound modifications. On the other hand, physical modeling and digital simulation formalisms have been principally used for the merely imitation and emulation of older sound processing systems. The aim of this paper is to propose three physical models conceived to offer sound modifications that mainly alter the amplitude of audio signals. The originality of this case is not the resulted audio modifications but their transposition in the framework of physical modeling and digital simulation, which outlines an alternative control procedure.
