Polyphonic Ringtones

Polyphonic ringtones are a major improvement on these old-style ringtones. Created from a MIDI file, polyphonic ringtones use a little synthesizer chip inside the mobile phone to achieve the various instrument sounds such as drums, guitar, keyboards, bass, and so forth on multiple tracks. The chip approximates the sounds of these instruments, resulting in a semi-realistic version of a song.

Unfortunately, polyphonic ringtones are still unable to play an accurate and convincing reproduction of the original music. Nevertheless, 80% of mobile phones currently use MIDI-created polyphonic ringtones.

The Future of Ringtones
Needless to say, the quality of ringtones is continuously improving and evolving in cell phone audio technology. The latest incarnation are real music ringtones, capable of playing the actual music, including the vocals and accompaniment. Most older cell phones are unable to play real music ringtones, while newer more expensive cell phones can handle real music ringtones or MP3s.
