Sometimes, listening to a new favourite track on your iPhone isn't enough. If you feel the need to bestow listening pleasure on others and make people around you aware of your cutting-edge taste in music, setting your latest musical flavour of the month as your handset's ringtone will be right up your street. It will take a little fiddling around as you can't set whole tracks as iPhone ringtones, but seeing the looks on people's faces when your handset starts to blare out your chosen tune will be well worth the effort.
Open iTunes, right-click on the song you want to use as a ringtone and select "Get info."
Click on the "Options" tab and mark the "Start time" and "Stop time" tick-boxes. Select a 30-second section of your chosen track. This will be your ringtone. If you don't want to use the fist 30 seconds, have a few listens to help you choose which section you want to use. Set your "Start time" parameter where you want your ringtone to begin, your "Stop time" parameter 30 seconds later and then click "OK."
Right-click on your original track again from your music library select "Create ACC version." iTunes will create a new 30-second clip of your chosen track that should appear below the original in your music library.
Drag the 30-second clip of your track to the folder where you store your ringtones and then delete it from your iTunes library. Right-click on your original track and reset its parameters.
Right-click on your converted track snippet in its new location and change its extension from ".m4a" to ".m4r." Double-click the file to add it to your iTunes ringtone library.
Connect your iPhone to your computer, sync it with iTunes and then navigate to its ringtones library to set your song clip as your ringtone.
