MP3 audio also known as MPEG audio layer 3 is probably the most popular type of ring tones. This is one of the compression techniques for digital audio forms. Unencrypted, crude audio forms can take a bulk of your space, hence a compression method must be used to encrypt this data and still maintain the information inside it.
MP3 is one of such compression methods. MP3 is very effective since it uses the technique where sounds that are not important and audible to human ear are dropped before the audio can be compressed. MP3 is the best choice among compression techniques for making a truetone ringtone. The reason is that MP3 uses very little space to store large quantities of data. And for the same reason, MP3 ringtones are gaining popularity, and being widely used in mobile phones these days. The users can create their own MP3 from any digital audio media. Thus the users can get what they want whenever they want.
There are a lot of softwares (sharwares and freewares) that allow you to rip music from the digital media to any form that you want it to be. Thus it is very easy to create your own MP3 ringtone. But, before even trying to create an MP3 of your own, check if your mobile phone can even play the MP3 format or not. Not all phones have this capability. When you are sure that your phone is equipped with the essentials of playing an MP3 form of sound, you can go ahead and create an MP3.
When you have finished creating a truetone ringtone on your computer, you can get it into your cell phone using either the data cable or Bluetooth or the GPRS facility that may be acquired from your service provider.
Like other types of ringtones, MP3 ringtones are also available for download from the internet. They are usually free but sometimes may cost a small fee. Creating your own MP3 ringtone for your phone is a more creative and a better idea than buying one. But just a gentle reminder, do not override the copyrights of any tune that you download from the internet.
