iPhone ringtone

I want the clap clap song as my ringtone on my iPhone but don't know how to convert it from mp3 to iPhone ringtone, anyone any ideas?

 

Some say apps out there but suggest use ringtone purchase for 69p

 

Type in you tube convert to iPhone ringtone and it tells you step by step that's where I got to know how to do it

 

Download Goldwave on your computer (http://www.goldwave.com/release.php) it's freeware, no viruses or owt, all legit
Install Goldwave
Open up the MP3 in Goldwave
Go to File > Save As
At the bottom, change the format from MP3 to m4a, save it somewhere
Go to the location of the file you just saved and rename the extension from .m4a to .m4r
Load iTunes up, open the ringtones section, drag and drop the m4r file in there
Sync iPhone, it'll appear under ringtones
