Abstract

In multimedia products, graphical and audio objects enrich textual information. Combining these elements correctly makes it easier for users to interact with the software. Usually, multimedia authors focus on the graphical objects rather than sound, which complements an image or provides a musical comment to text and graphics. While the demand for increased interaction with programs has helped the visual part evolve, the paradigm of using audio hasnt changed adequately, resulting in several different objects rather than a continuous transformation of these objects. A more intensive use of digital audio effects will let sounds adapt interactively to different situations, allowing users to enjoy the product even more. We believe that the evolution of audio interaction promotes the use of expressive content. Such an interaction should allow a gradual transition (morphing) between different expressive intentions. Recent studies have demonstrated that its possible to communicate expressive content at an abstract level, which can change the interpretation of a musical piece. In fact, in human musical performance, the performer organizes acoustical or perceptual changes in sound to communicate different emotions to the listener. The same piece of music can be performed by differently by the same musiciantrying to convey a specific interpretation of the score or the situation by adding mutable expressive intentions. Similarly, were interested in having models and tools that let us modify a performance to change its expressive intention. Our study of the expressive content of audio led us to develop a system for the auralization of multimedia objects for Web-based applications.
