Digital signal processing and audio synthesis for sound design

Sound design is a relatively recent field of design, based on an approach that aims to consider the sound component right from the design phase of an object in order to make an intention audible; or, to put it another way, and to quote Louis Dandrel, a discipline that mainly consists of designing with sound. Its raw material therefore addresses issues of generation, representation, transformation... in other words, the manipulation of a sound object that is most often digital – or digitised – and for which signal processing and sound synthesis are essential and fertile tools. More specifically, one of the major issues in the sound design process concerns the transition from ideation to realisation. The question is how to move from a symbolic representation (graphic, semantic or even simplified audio) to a sound artefact – even at the sketch or prototype stage – capable of meeting functional and aesthetic specifications. This often weak but crucial link in the design process will be explained and illustrated by experiments and implementations carried out as part of various research-project approaches that have enabled us to acquire new knowledge in the field as much as to provide solutions to an applied problem.
