What is MP5

Voice compression technology also plays an important role in current consumer products. It can be used in everything from Internet phones to toys, and it is also based on Different technologies have been developed for different application areas. MP5 is the abbreviation of MPEG Layer 5. It is an algorithm developed by domestic technology manufacturers.

MP5 music is a sound effect file format. It can actually convert a complete wav, mp3 or cda sound file through MP5 compression technology to produce a compression ratio of about 1: 10 music sound files.

Everyone should know that a dog’s ears can hear the sound of a train far away, or the barking of another dog three streets away, but humans cannot hear it. This is because human ears are different from dogs. The difference between dog ears is that dog ears can hear higher frequency sounds than humans.

In addition to the frequencies that humans can hear, general sounds and songs contain frequencies that are inaudible to humans. Human hearing has its innate limitations. Generally speaking, there are two types of sound signals that the human ear cannot detect. One is higher or too low frequency, and the other is weak music that strengthens the signal. If these signals in the sound that are inaudible or imperceptible to the human ear are filtered, In addition, the storage space required after digitizing the sound can be significantly reduced.

The MP5 compression algorithm filters out these imperceptible sounds in advance for the user and greatly reduces the storage space required after the sound is digitized. Using the MP5 compression algorithm to process music is a special compression method, and because of this, a high compression ratio can be achieved.

The result of using this special compression is that it will inevitably cause a little distortion when restoring the sound effect, but these distortions are within the acceptable range of the human ear. However, when the compression ratio is too high, the distortion produced There will be more. The MP5 compression technology is to eliminate the sound frequencies that are inaudible to human ears to achieve the purpose of compression.

As a result, some parts of the original sound are lost, and the sound file size is reduced. This is the principle of MP5 compression technology. MP5 uses special compression technology, which makes it difficult for us to detect it, because its compression makes it sound like it has not been compressed.

MP5 compresses WAV, MP3 or CDA songs into short and easy-to-manage music files. Without damaging the sound quality, a WAV music file of more than 40 MB can be compressed into 4 MB. MP5 songs; a CD that can only store a dozen songs can store more than a hundred MP5 digital music, and the sound quality is almost the same as MP3 music.

In the past, downloading a complete song through the Internet was an unrealistic idea, because the variety of music formats and their huge file sizes further hindered the dissemination of digital music on the Internet. But with the advent of the MP5 format, downloading an ordinary song no longer takes half an hour, but only takes two or three minutes.

The advantages of MP5 are not only that, the sound quality of compressed music is no worse than that of MP3. MP5 uses a "special compression algorithm" to filter out sounds that humans cannot hear to gain more storage space. Therefore, music compressed with MP5 technology should strictly speaking be slightly worse than MP3, but it is just invisible to the listener. That’s all.

MP5 music files have many advantages. Because the file size is small, they can be better utilized for network transmission. The portability of MP5's pure digital and pure data computers and the divisibility of music data are also unmatched by traditional CDs. Basically, you will find some problems using traditional CDs.

For example, if you only like a few songs on a CD, but you have to buy it together with the other songs you don’t like, it is not only a waste of money, but also causes trouble when replaying and enjoying it. With the help of MP5 music files, users can also create their own MP5 music collections, which is more convenient than traditional CDs.

Looking at the method of MP5 dissemination alone, using portable MP5 playback devices to replay music files, the digital music playback method is more convenient to operate than the traditional CD player. It's faster than CDs, and you don't have to worry about needle skipping due to vibration. Because it's purely digital, it saves more power than CDs, and it can be smaller and lighter than CDs.
