Audio component group

The audio component group is a discrete component group for the management of audio items that form stimulus components (or that form part of more complex component groups or components). Each audio item can be associated with factors and levels and can be formatted and manipulated via variables. The screen contains a section on the left hand side for managing audio items and a section on the right hand side for managing variables. The splitter (Figure 1) can be dragged to to allow customization of the screen layout, and the chevron left symbol button on the top of the splitter expands and chevron right symbol collapses the panel.
