What is a constant bit rate?

4 This is against variable bit speed (VBR) where the bits can be changed to match different types of files and quality level. While many people complain of a bit rate of constant bit speed, it's useful for those who want a consistent level of quality, and those who need to monitor the amount of bits used in files. The main complaint about CBR is that it uses a number of bits that do not contribute to the quality of the file.

Constant bit speed means that when the file is coded, it will be encoded at the same bit rate, so the amount of bits depends on the file size, not the quality or type of file. Although this is not entirely true - some types of files will contain multiple bits that other types of files - this amount differs by an insignificant amount. With CBR, the quality level is the same for sound, video or document, regardless of whether the file is complicated or simple.

isI do for the use of a constant bit speed is that operators and users are provided most compatibility, especially when using online. Some online streaming programs and websites allow VBR, but all allow the use of CBR. Using the CBR current, the user will be able to send the file via any streaming system without worrying that he will have to exclude any website.

Another Pro is that users can accurately estimate the amount of bits per file when using a constant bit speed. This advantage will not be useful for ordinary users, but professional users who are hired to codes files, and users who optimize their computers consider it useful. The user will be able to maximize the amount of files available on the computer. The

quality is also consistent between files coded with constant bit speeds. It can be good, or unstable, depending on the file. For example, if there is a complex part of the song, such as the part whereIt is a complex guitar solo, the amount of bits used for this part will be the same as the silence, which usually occurs in the songs at the beginning and end. Although it may be a problem, most users and listeners will not notice much. People who argue about VBR files say that CBR does not use enough bits for complex portions and too much for simple portions.
