What are the formats of music?

Music formats include: MP3, MIDI, WMA, VQF, AMR, etc.

1、MP3

MP3 format was born in Germany in 1980s. The so-called MP3 also refers to the audio part of the MPEG standard, that is, the MPEG audio layer. According to the difference of compression quality and coding processing, it is divided into three layers, corresponding to * .mp1* .mp2/* .mp3 respectively.

2、MIDI

MIDI (Musical Instrument Digital Interface) format is used by people who often play music. MIDI allows digital synthesizers to exchange data with other devices. The MID file format is inherited from MIDI. The MID file is not a recorded sound, but a set of instructions to record the sound and then tell the sound card how to reproduce the music.

3、WMA

WMA (Windows Media Audio) format is a heavyweight from Microsoft, with strong background and better sound quality than MP3 format, even better than RA format. Like VQF format developed by Yamaha Company in Japan, it aims to achieve a higher compression ratio than MP3 by reducing data flow but maintaining sound quality.

4、VQF

Another format of Yamaha Company is *. VQF, its core is to reduce data traffic while maintaining sound quality to achieve higher compression ratio. The audio compression ratio of Vqf is nearly twice that of standard MPEG audio compression ratio, which can reach 18: 1 or even higher.

5、AMR

The full name of AMR is Adaptive Multi-Rate, which is mainly used for audio of mobile devices. The compression ratio is relatively high, but the quality is poor compared with other compression formats. Because it is mostly used for voice and phone calls, the effect is still very good.
