Wechselspieler -- General information

Screenshots and work samples

Since the Gnome screenshot utility can not grab the content of overlay buffers only one screenshot for first. You have to imagine a video image instead of the blue box on the left. The screenshot gives an impression of the main GUI elements in version 0.1 of wechselspieler:



Fig. 1: The main GUI elements. Main window (top), binarisation dialog (botton left), region/trigger preferences for the first region, selected in main window (botton right).



Fig. 2: The main window with configuration dialogs for each region grouped around it, as in version 0.4.

Those who are curious about what Wechselspieler is good for, a Quicktime movie (5.2MB) gives an impression of what can be done with the software. Although it is artistically not that sophisticated it shows the key point of wechselspieler: Generating sound from video. In this case, the waves of the ocean play a simple tune.
