Music formats include: MP3, MIDI, WMA, VQF, AMR, etc.
1. MP3
The MP3 format was born in Germany in the 1980s. The so-called MP3 refers to the audio part of the MPEG standard, which is the MPEG audio layer. It is divided into 3 layers according to the difference in compression quality and encoding processing, corresponding to the three types of sound files: *.mp1/*.mp2/*.mp3.
2. MIDI
The MIDI (Musical Instrument Digital Interface) format is used by people who often play music. MIDI allows digital synthesizers and other devices to exchange data. The MID file format is inherited from MIDI. The MID file is not a piece of recorded sound, but a set of instructions that records the sound information and then tells the sound card how to reproduce the music.
3. WMA
WMA (Windows Media Audio) format is a heavyweight player from Microsoft. It has a strong background and its sound quality is better than MP3 format and far better than RA format. It is similar to Japan The VQF format developed by Yamaha Company is the same. It achieves a higher compression rate than MP3 by reducing data traffic but maintaining sound quality.
4. VQF
Another format from Yamaha Company The format is *.vqf. Its core is to achieve a higher compression ratio by reducing data traffic but maintaining sound quality. The audio compression rate of VQF is nearly double that of the standard MPEG audio compression rate, which can reach about 18:1. Even higher.
5. AMR
The full name of AMR is AdaptiveMulti-Rate, adaptive multi-rate coding, mainly used for audio on mobile devices. The compression ratio is relatively large, but the quality is relatively low compared to other compression formats. Poor, because it is mostly used for vocals and calls, the effect is still very good.
