Older telephones simply used a pair of bells for the ringer. Modern ring tones have become extremely diverse, leading to phone personalization and customization.
Newer mobile phones allow users to associate different ring tones with individual family members and friends. Taking advantage of these features, a new ring tone maker trend has emerged. For example, websites like Mobilephoria, Phone Sherpa, and Dopetone let users make ring tones from the music they already own (MP3, CD etc.) and upload directly to their mobile phone with no limit on the number of songs uploaded. In addition to the cost benefits, a key feature is the music editor that lets the user easily pick the part of the song they wish to set as a ring tone. Such services automatically detect the phone settings to ensure the best file type and format. There are, however, providers who have already edited and trimmed the song for you.
Some providers allow users to create their own music tones, either with a "melody composer" or a sample/loop arranger (such as the MusicDJ in many Sony Ericsson phones). However, these use native formats only available to one particular phone model or brand. Other formats, such as MIDI or MP3, are often supported; they must be downloaded to the phone before they can be used as a normal ring tone. Commercial ring tones take advantage of this functionality, which has led to the success of the mobile music industry. Southern rapper Chamillionaire was the first to have a ring tone go 3x platinum for the hit single "Ridin." He now has his own category on certain phones.[citation needed]
The latest innovation is the sing tone, a type of karaoke ring tone where a user’s voice recording is adjusted to be both in time and in tune then mixed with a backing track to make a user-created ring tone.
