MIDI sequence

Sound) is the multimedia data form of SMF (standard MIDI file). Just like the music score used by the symphony orchestra, it only records the information of when and what instrument to use, as well as the longer chord. MIDI information occupies a relatively small space, which is very suitable for use in mobile phones, but its biggest disadvantage is its low volume, but now some software can be found online to adjust it.

self-adaption

Multi-Rate) is a speech compression format applied to mobile phones, that is to say, the files we record with mobile phones are in this format. AMR format has high compression rate, but the sound quality is slightly poor. The advantage is that you can record at will.

wave form

Audio) is a standard audio file format, but compared with other compressed files, it takes up a lot of storage space, but it is very outstanding in sound quality. If your mobile phone has enough memory, it is still very valuable.

encode

Standard), which can compress the general uncompressed music data to the size of 1: 10 to 1: 12, and keep the distortion rate almost indistinguishable from the human ear. However, compared with mobile phone products, MP3 still takes up a lot of memory space, so mobile phones that support this music (ringtone) format generally have relatively large memory space or can expand external memory.
