Ring tone format:

Popular ringtones in 2002 include mp3 ringtone, chord ringtone, midi ringtone and wav ringtone. With the upgrading of mobile phones, new phones even support APE ringtones. Because MIDI is the basis of all ringtone formats, quite a few mobile phones in 1988 adopt or are compatible with MIDI format.

Later, mobile phone manufacturers gradually began to adopt Yamaha chips, and mobile phone enthusiasts began to be interested in real people singing ringtones, so MMF format ringtones also occupied a part of the share. With the continuous development of mobile phone ringtones, the disadvantages of short playing time of MMF are slowly emerging.

Sony Ericsson and other mobile phone giants have launched a new live-action singing form AMR. This format of ringtone plays for a long time, but the sound quality is relatively poor. Mobile phone ringtones have developed to 10, and MMF, AMR live singing, MP3 and WAV file formats have gradually become mainstream formats.

The ringtone format of Apple's mobile phone is m4r format, which is a special format for Apple's mobile phone system.
