Audio themes feature allows you to personalize the user interface sounds of your phone. Audio themes are offered in packages which contain several sound files of a common theme. The packages contain usually the normal profile sounds (e.g. ringing tones, message alerts, clock alert, calendar alarm) but also sounds for phone handling (e.g. fold open, fold close) and menu events (enter menu, leave menu).
Your phone supports audio themes if you can find this icon in the menu (personalization/themes). If your phone doesn’t supports audio themes you can still download and use the ringtones ripped from N8 Audio Themes pack. Corresponding Audio Themes and their Ringtones are packed in respected zip files.
