Acronym for Variable Bit Rate.
VBR (Veriable Bit Rate), this term, which means “Variable Bit Rate” is a file extension created by Visual Basic, which is used to calculate bit rates in audio and/or video encoding. VBR files are created when an application is compiled. These VBR files contain information that will enable client machines to use the remote application.
To explain with a good example; The values of 128 and 320 kbps, which express the sound quality and depth of our music in .mp3 format, brought new needs along with the developing technology. There is a significant difference between the sound quality and depth on stone records and our music in digital media. One of the most important reasons for the sound quality factor is the need for storage space. So, considering that stone records only took 1 (one) song on each side, it would store a total of two highest quality songs.
VBR, on the other hand, is a code structure created to solve the problem of increasing file size as the quality increases. VBR gives more complex sections a high bitrate, allowing it to take up less space. To continue with the stone record example, it would have allowed the stone record we gave in the example above to have more than one song on one side with the same sound quality.
Audio files such as MP3, WMA, AAC, Vorbis, Opus can be optionally VBR encoded. Variable bitrate encoding also supports commonly used MPEG-2 video MPEG-4 Part 2 Video (Xvid , DivX etc.), MPEG-4 Part 10 /H.264 video Theora , Dirac and other video compression formats.
