MP3 is one of the encoding format to compress digital audio. Initially it used Constant Bit Rate (CRR) to compress an audio file. But, only audio layer 3 MP3 encoders like “LAME” can produce Variable Bit Rate (VBR) audio. VBR encoders are used to ensure a fixed level of quality as it can switch bit rates on each audio frame.
