Properties of Visualizations


Properties of visualizations can be changed in a property editor (see figure) which is divided into two sections: (1) A navigation toolbar and (2) a property-value editor. By clicking the buttons in the navigation toolbar you can "navigate" inside audio files (i.e. change temporal and bandwidth properties of visualizations). These properties may also be changed by clicking the scrollbars of the VIS-Editor or by using shortcuts. Some changes in the property editor are executed instantly.
