WAVE: Sound and music in an immersive environment

This paper presents WAVE—a Virtual Audio Environment, which embraces the implementation of an immersive musical instrument model that uses three-dimensional (3D) sound techniques combined with visualisation and virtual reality technologies. This prototype environment aims to extend the idea of a musical instrument into a new musical/audio system, incorporating traditional musical concepts side by side with actual music concepts, in order to progress one step further in the music/sound composing and performing approaches.

The architecture of the system is based on low-cost hardware and open source software with affordable professional audio equipment to maintain an adequate sound quality. Also several applications of this virtual environment are discussed in the paper, including the way to satisfy at the same time composers, performers, music/audio students or even simple occasional users.

Testing software without requirements: using development artifacts to develop test cases

SourceForge, the world’s largest development and download repository of open-source code and applications, hosts more than 114,500 projects with 1.3 million registered users at this writing. These applications are downloaded and used by millions across the globe. However, there is little evidence that any of these applications have been tested against a set of rigorous requirements and indeed, for most of these applications, it is likely that no requirements specification exists. How then, can one test this software? In this work an approach is presented to create a set of behavioral requirements to be used to develop test cases. These behavioral requirements were developed for a small number of projects derived from SourceForge using artifacts such as help files and software trails such as open and closed bug reports. These artifacts highlight implemented product features as well as expected behavior, which form the basis for what we term behavioral requirements. The behavioral requirements were then used to create test cases, which were exercised against the software. The contribution of this work is to demonstrate a viable technique for testing software when traditional requirements are unavailable or incomplete.
