The demo version of Rubber Band Audio contains all of the processing goodness of the full application, and produces identical high-quality output.
Of course, it has some limitations. You can only save one file during each run of the application. You can't export files by drag-and-drop in this demo, or adjust a set of audio files at once, as you can with the full version. And it only has a single, default colour theme instead of the selectable theme of the full version.
