make ring tone from mp3

Making your own ring tones isn’t too difficult if you have a mobile phone that supports MP3 ring tones and a way to transfer files onto the phone from your computer. If you’re not sure about either, check your phone’s manual or wireless carrier’s Web site for the technical specifications for your phone model.
One of the simpler ways to make and install your own ring tones is to use software dedicated to the task. Programs like ToneThis (free at www.tonethis.com) for Windows or Xingtone Ringtone Maker for Windows and Mac OS X (xingtone.com; $20 to buy, free trial available) are options.
These types of programs let you edit the sound clip of your choice to the appropriate length and send it to your phone as a file download that you can assign as a ring tone. Most ring tone software makers list phone models and carriers on their Web sites so you can make sure your handset is compatible.
You may also be able to convert and edit a CD track or MP3 file with free or inexpensive audio programs available around the Web if your computer doesn’t have any sound-editing software already installed. Audio Shareware sites like HitSquad (www.hitsquad.com) and Audio Utilities (www.audioutilities.com) are two such sites. The open-source program Audacity (audacity.sourceforge.net) is a free audio editor for Windows, Mac OS X and Linux systems, but you need to download the program’s optional LAME MP3 encoder to export edited MP3 files.
Once you have edited your new ring tone with your audio program, you can transfer it to your phone as you do other files — U.S.B. cable, Bluetooth connection and e-mail download are some methods available. Check your phone’s manual for instructions on transferring audio files to the proper place for use as ring tones.
