Editing Time-Varying Spectra
Time-varying spectral analysis is a useful tool for working with sound. Unfortunately a very large amount of data is involved. A menu-driven graphics-based editor for time-varying spectra has been implemented at the Center for Computer Research in Music and Acoustics (CCRMA), Stanford University. The features that have been developed for examining and modifying spectra are outlined, and suggestions are offered for the next generation of editors of this type.
