After the 20th century, with the advent of computer technologies, composers initiated the use of electronic sounds in their musical pieces. Spectral school is one of the significant trends in contemporary music since the 1970s. Composers in spectral school use the acoustic properties of sound spectra as their key composition materials. One of the representative software systems they use for spectral analysis, sound processing and synthesis is AudioSculpt. We have developed an accompanying system with AudioSculpt to represent the history of creating sounds with spectral analysis of sound materials and processing of sound spectra using various filters by stacked spectrogram space whose axes represent the elapsed time of the sound and the progress of composition. The present system can be regarded as an initial attempt at managing the provenance of designing sounds in information visualization field.
