Thanks to technology, music has spread everywhere. Whether using phones, computers or radio devices, people can easily access music products. But did you know, the music quality is vastly different. Why does 128 kbps not sound as good as 320 kbps? This is the difference between the sound quality?

Megabit per second (English: megabit per second; abbreviated as Mbps), is a unit of measurement of data transmission speed, equivalent to 1,000 kilobits per second or 1,000,000 bits per second.

Kilobit per second (English: kilobit per second; abbreviated Kbps) is a unit of measurement for the speed of data transmission, equivalent to 1000 bits per second.

The bandwidth of a residential Internet service is usually measured in Mbit/s.

Kbps = kilobit per second = is a unit of measurement of data transmission speed. The higher the number, the higher the sound quality of the song. It is divided from 8 to 320.

Kbps is collectively known as bit-rate. That is, the number of bits the computer needs to process in one second. For example 128 Kbps music, the computer has to process 128000 bits per second. It is because 1Kbps = 1000 bps. The same is true for 320 Kbps music, the computer will have to process more than 320000 bits/second. What is 256 kbps? It is the music that the computer has to process 256000 bits/second.

Bit-rate in music has 3 basic types as follows:

Constant bitrate (CBR):

128, 320Kbps music on music sites like zingmp3, nhaccuatui is encoded with this CBR. This is a fixed bit-rate. That is, whether it is a piece of music without lyrics or with lyrics, in the same song or in many songs, the computer processes it with a fixed parameter. Here is 128 or 320 Kbps. Then the computer will waste CPU leading to music file size. But many passages lack practical bass.

Average bitrate (ABR):

This is a custom bit-rate. Because kbps will be changed to suit the music with different bass details. For example, the gentle passages have a low bit-rate, and the strong segments have a high bit-rate. This helps optimize CPU. ABR has just created authentic music with the same capacity as CBR’s. So the conclusion is that the customization ability of ABR is not very good.

Variable bitrate (VBR):

This is the most optimal bit rate. It is much more evolved than the ABR. Thereby minimizing the waste of CPU. The encoded track is also more realistic and has depth. At the same time, the VBR music file is the smallest, much more optimized than ABR and CBR.

* Note: Since VBR encoding is a bit-rate variable encoding, we should call MP3 music of this type MP3 -V (x) with (x) replaced by numbers from 0 to 9, which is the order of quality. VBR with -V 0 = highest quality and -V 9 = lowest quality. For example, with the name MP3 -V 0, we understand that it is the highest quality MP3 VBR file, not called 128 or 320 Kbps like CBR or ABR.

Music quality order of encoding types (low to high):

MP3 128Kbps (CBR) » MP3 320Kbps (CBR) » MP3 ~320Kbps (ABR) » MP3 -V 0 (VBR) » OGG -q 1 (VBR) » Nero AAC -q 1.00 (VBR) » LOSSLESS

Order of music file size of the same track (from low to high):

MP3 128Kbps (CBR) » MP3 -V 0 (VBR) » MP3 ~320Kbps (ABR) » MP3 320Kbps (CBR) » Nero AAC -q 1.00 (VBR) » OGG -q 1 (VBR) » LOSSLESS

Downloading music 128 kbps means the music you downloaded is of normal quality. At the same time, the capacity is also quite small.

Usually, 128 bit rate versions online are free to download. Music websites will charge for download with higher quality such as 320 kbps, lossless, …

1 Mbps English is 1 Megabit per second ~ 1 Megabit per second.

A unit of measurement for the speed of data transmission, equivalent to 1,000 kilobits per second or 1,000,000 bits per second.

1 MBps English 1 Megabyte per second ~ 1 Megabyte per second.

is another unit of measurement of data transmission speed, often used to exchange data between computers or between computers and other peripheral devices (USB, hard drive, optical drive)

Hopefully after this article, everyone will understand more about the quality of the music they are listening to. As well as a unit of measurement of data transmission speed.
