This research project aims at developing a set of software tools for people working with sound design and that have a limited experience of it. The tools will help the users create sounds for specific contexts and environments. Today there are no simple programs available for the design of sound for a user-defined environment compared to what can be found in the field of graphic design. The tools will be a professional design aid for audio signals, audio content and audio landscapes within a perceived environment. This enables virtual placement and choice of sound sources.The software for simulating sounding environment is under development and will be released during 2010.
