Are you really about to fork out more money for 15-second clips of your favorite songs? We don't think this is fair and to right this injustice we show you how to make your very own iPhone ringtones for free. All you'll need is an iPhone 4S(of course), iTunes and a swag of MP3 files.
Foxreal Video Converter helps you to drag audio tracks from movie files or convert other audio files to MP3 audio. There are three steps to convert an MP3.
1. Open Video Converter and import the source file (either video or audio) by clicking the icon on top-left corner of the interface.
2. Click “Settings” and select the profile of MP3 in Common Audio section. Then click OK.
3. Choose output directory and start conversion.
Once the conversion finished, do as following to make your own iPhone ringtones:
1. Open iTunes and add your converted MP3 audio file to library.
2. Right-click (Cmd-click for Macs) on this file in your library to bring up the context menu.
3. Select Get Info. This will open a new dialogue box showing various details about the audio file. Select the Options tab.
4. Check the boxes next to both Start Time and Stop Time and enter the times you want your new ringtone to start and stop (the maximum length is 40 seconds) then click OK.
This will return you to your music library.
5. Right-click (Cmd-click) on the same music file again and this time select Convert Selection to AAC. iTunes will process this briefly and insert the new ringtone-sized file under the original file in your library.livepage.apple.com.
6. Right-click (Cmd-click) on the newly created file and select: "Show in Windows Explorer (or Finder on a Mac)"
A new dialogue box will open showing you the location of this file. Select the file and rename it, changing the file extension from ".m4a" to ".m4r". Windows will warn you that this change may make the file unstable, but continue anyway.
Back in iTunes, delete the ringtone file you've created from your library, then import the renamed ".m4r" file into your library. Connect your iPhone 4S and sync your playlist. You may have to manually drag the .m4r file into the Ringtones section on your iPhone 4S. With your iPhone 4S synced this file is now ready to be used as a ringtone.
