VBR Definition - What is VBR?
What does VBR stand for?
The bitrate of a digital audio file refers to how much storage space, per second of audio, is used up by the audio track. The lower the bitrate, the lower the file size, but also the lower the quality of the audio. Variable Bit Rate, or VBR, refers to a file which is compressed so that the bitrate fluctuates throughout the track, resulting in a compromise between small file size and quality loss. The bitrate will be higher during parts of the file where more frequencies are being utilized, and it will be lower in parts of the file where less frequencies are being utilized.
