Sculptor: Exploring Timbral Spaces in Real Time

摘要

Characterization of the timbre of a sound from its spectrum or time series is of limited use in the context of electroacoustics because of the huge data set that is usually involved. The concept of a timbral space offers the potential to characterize sounds using a smaller Set of variables, but it is not clear how the signal-derived parameters map onto their Psychoacoustic correlates. Sculptor is a package that enables the analysis, parameteriza- Tion, and editing of sounds in real time, requiring only inexpensive hardware. State-space Techniques are used to decompose models of a selected sound into parallel second-order Sections.
