Ring tone format:

In 2002, popular ringtones included mp3 ringtone, chord ringtone, midi ringtone and wav ringtone. With the upgrading of mobile phones, new mobile 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 formats.

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

Sony Ericsson and other giants in the mobile phone industry 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. Cell 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 mobile phone is m4r format, which is a special format for Apple mobile phone system.
