iOS

Create own ringtones of any mp3 in iTunes:
1. Öffnen Sie iTunes und wählen Sie in der Menüleiste iTunes -> Einstellungen.
2. Unter Allgemein -> Importeinstellungen -> Importieren mit wählen Sie AAC Codierer. Unter Einstellung wählen Sie Höhere Qualität. Bestätigen Sie mit OK.
3. Wählen Sie das gewünschte Lied in iTunes aus. Beachten Sie, dass diese Anleitung nicht mit offline gespeicherten Apple Music-Liedern funktioniert.
4. Machen Sie einen Rechtsklick auf das entsprechende Lied und wählen Sie Informationen.
5. Im Reiter Optionen stellen Sie die gewünschte Zeitspanne ein, die Sie als Klingelton haben möchten. Achtung: Der Klingelton darf maximal 40 Sekunden lang sein.
6. Bei einem weiteren Rechtsklick auf das Lied wählen Sie AAC-Version erstellen aus. Jetzt sollten sich in Ihrer Mediathek zwei Lieder befinden – einmal die Ursprungsversion und einmal die neue mit der richtigen Zeitspanne.
7. Klicken Sie nun rechts auf die neue, kurze Version und wählen Sie Im Finder anzeigen.
8. Damit iTunes die Datei als Klingelton erkennt, müssen Sie das Dateiformat ändern. Benennen Sie die Datei um: Die Endung „m4a“ wird zu „m4r“.
9. Öffnen Sie iTunes erneut und löschen Sie die in Schritt 6 erstellte AAC-Version.
10. Unter Ablage -> Zur Mediathek hinzufügen navigieren Sie zur erstellten m4r-Datei. Markieren Sie diese und bestätigen mit Öffnen.
11. Nun können Sie Ihren neuen Klingelton mit dem iPhone synchronisieren.
