This app is a sonified version of the Notes example code, and is intended to demonstrate the use of game audio techniques to vary system sounds, as described in my O'Reilly blog Generating Audio UI for Android (

). It algorithmically constructs diverse sounds from short clips when opening or closing the app, the menus, and the notes. Three different audio Themes are supported.
