WinSingad: a real-time display for the singing studio

This paper describes the nature and implementation of a specially-designed integrated real-time display that is undergoing evaluation as part of a recently funded innovative pilot project to investigate the relative usefulness of computer displays in the singing studio. Following previous work that suggests that simple displays of a small number of analysis parameters are generally likely to be the most effective, the system makes available a range of complementary analyses that are plotted against time. These relate to: fundamental frequency, spectrum, spectral ratio, and vocal tract area. These can be viewed singly, multiply or in combination using a panel based design within the PC Windows environment, known as WinSingad. The algorithms used are described and the displays themselves are illustrated with results gained from the pilot phase of the research to indicate their potential usefulness.
