Many Sounds of Ringtones

We are surrounded by computerized technology whether it is a PDA or a cell phones. These gadgets also have personalized built-in materials that can be a bunch of fun at home, such as videos and video games. Now we have our personalized soundbyte—that is—our cell phones.

Welcome to the world of ringtones. There are some ringtones that are very pleasing to the ear. At the same time, there are those tones that are just plain horrible and irritating.

Ringtones are meant to allow the cell phone users to have the soundbytes that match our personality along with letting the phone's ring be different from other cell phone customers.
But how does these ringtones come to life? It is pretty simple, but if anyone is not really musically-inclined, then it may sound a little bit difficult.

These sample pieces of soundbytes is from a computerized program that is in the cell phone's memory clip. The purpose of this memory clip is to tell what the microprocessor what the speaker system on the mobile phone should do in case during an incoming call.

Remember music class? I have a very vivid memory of music class, learning about first note and second note. The same thing applies to ringtones on cellular phones. These have a number of notes that are in the phone's memory. In other words, there is information about different frequencies that will create these very distinctive ring sounds. The microprocessor is told to play a particular tune in a certain order and speed. On the cell phone, the microprocessor can play unlimited number of these soundbytes.

These tones also come to life by a program language known as RTTTL, or Ringing Tone Text Transfer Language. This was brought to life by Nokia. The following are the representations of duration and octaves on the cell phone ringtones:

On the duration side, one represents a full note while two represents a half note. There are also the quarter note, eighth note, the sixteenth note, and the thirty-second note. In contrast to the duration, there is the octave. The octaves are represented in hertz and kilohertz. For example, octave number five is the representation of A, which is four hundred forty hertz. Octave number six is eight hundred eighty hertz. Getting past the sixth octave, we are getting into kilohertz. The seventh octave is 1.76 kilohertz and the eighth octave is 3.52 kilohertz.

Of course, there are many different software applications in which ringtones can be customized. I am very open to creating some unique soundbytes. Let's see what other unique ringtones that individuals can come up with. Keep the ears opens because sky is the limit!
