The charts were created by hand, which was a laborious task. In TIAALS, the Chart Maker is designed to create these charts automatically using sections of the piece selected by the user. Re- gions to be included in the charts are selected on the Interactive Sonogram and added to a Palette of sounds. The regions can then be grouped on the Palette by the user before creating a chart.
