How to edit ringtones / system sounds
Creating ringtones is a pretty easy thing to do if you have a little patience. I will show you how
to do this using a free program called Audacity.
Apple has also provided a way to create ringtones via GarageBand.
Download Audacity here.
While you are at this page, download the LAME MP3 encoder. This will allow Audacity to export to
MP3 format. Once you've installed Audacity and started it, you'll see this screen.
Let's get a song to work on. Click File, select Import, then select Audio...
Select your song, and click Open.
You will now see what your audio file's waveform looks like.
I have expanded this size of the program so I can see more of the audio wave. Only the left channel
is viewable here. If you expanded the program screen further, you'd see the right channel. Keep
in mind, it's not my intent to teach you how to use this program. You're going to have to
experiment on your own. I also clicked the magnifying glass icon to zoom in on the audio wave,
so that I can select a section of it to use. You want your loop to be as clean as possible when
it repeats. As you can see below, I've already selected a section of the song (highlit in gray).
You can check the quality of your edit point, by clicking Transport, then selecting Loop Play. Just
click the stop button in the program to end playback.
When you are satisified, click File, Export Selection...
Change whatever information you'd like at this screen, and click OK.
Name your ringtone. Select MP3 Files as the format. Click Save.
You should now have your mp3 on the desktop.
Drag your mp3 into iTunes.
Right click your mp3 in iTunes and select Create AAC Version.
Drag the AAC version out of iTunes to your desktop. Delete the AAC version that is still in iTunes.
It will not allow you to import the ringtone we are going to make if you don't.
You should now have your AAC file (.m4a) on your desktop.
Click the file name and rename from .m4a to .m4r.
Click Use .m4r at this pop up message.
Now drag your .m4r back into iTunes.
Your ringtone has been added.
Sync your iPhone. It will be placed in your Custom section. If you'd like the mp3 version of the
ringtone I made,
here it is.
