If, like me, you are bored of your standard iPhone ringtones, here’s some simple steps to convert some of your favourite tunes into ringtones. OK, follow me…
1. Open iTunes and choose your track (you may want to duplicate it to avoid altering the original version)
2. Right-click (or maybe Control click, if you haven’t set up your Mac for this) to ‘Get Info’ on the song. The ringtone needs to be shorter than the original song, so adjust the stop time (and start time, if necessary) so the total length of the track is less than 30 seconds (see screenshot, below). You will find this under the ‘Options’ tab. Click OK

3. Right-click once again on the track and choose ‘Create AAC version’, if it isn’t already. If you can only see ‘Create mp3 version’, then alter your import settings in iTunes preferences and choose AAC Encoder (see screenshot, below). You will now see a shorter, AAC file underneath the original. It might be worth renaming the file at this point, eg. add ‘_ringtone’ before the file extension

4. Locate the file on your hard drive in your iTunes library. To do this easily, right click and choose ‘Reveal in Finder’ if you’re on a Mac (I think it is ‘Reveal in Windows Explorer’ on a PC). Keep this window open on your desktop. Click on the file in iTunes and press delete – when it asks to remove the file, choose ‘Keep File’
5. Change the file extension from .m4a to .m4r
6. If you haven’t already, tick ‘Ringtones’ under general preferences. Available ringtones will appear in the left-hand column in your iTunes window. Click ‘Ringtones’ and then drag your new ringtone file (.m4r) into this window
7. When you connect your iPhone to your computer, click on your phone icon, under devices and then Sync ringtones
8. Job done… you can now annoy your friends and colleagues with your unique taste in music every time your phone rings!
