This limitation can be frustrated, especially when you have got a complete music file, FLAC for example, that you want to convert it to .m4r format to make a ringtone for your iPhone. Obviously, the FLAC music is too long to create an iPhone ringtone. How do you shorten your sound track and save just a portion of it?
