I just got my iphone a couple days ago, and so I'm up at 2:30 in the morning trying to make ringtones to use for it. I can take copies of my music in itunes and change the extensions to .m4r files but a 3:30 minute ringtone doesn't do me much good....I tried to use the program Audacity to edit my music, but it won't work for some reason. Audacity has you convert the files to WAV then edit them but after I edit them and change the extension, itunes won't open it. Is there something I'm doing wrong or is there another program that I could use that I could use to just edit the m4a files instead. Thanks for the help in advance!!
