We have developed a visualization technique for music similar to an spectrogram in that it presents its time and frequency content, but with the advantage of a multi-timescale aggregation that offers at-a-glance information interpretable as the global timbre resulting from a normative performance of a score, and without the need for an acoustic representation of that music.
In the examples so far, scoregram proved useful in the detection of musical structure. We believe that it could also be used to establish measures of similarity between repertoires, or comparisons between the precisely observable acoustic event and its notated counterpart, which could help in the quantification of a performer's contribution.
Woonogram is a sound visualization mapping scheme that generates animations of polygons from the spectral information of sound. Although based on a set of simple rules, it produces evocative animation of sound through spectral analysis while providing flexibility and variety thorugh simple changes of parameters. Recently implemented features include automatic transition of mappings and loudness compensation for display.
Since its first introduction in 2001, Woonogram has been employed for creation of multimedia artworks.
