If a decoder expects the same number of bits every second, this can really confuse it! Greater bit rates generally mean better sound quality and a closer representation of the original sound. With variable bit rate MP3s, the encoder automatically detects which bit rate is most apropriate for the sound being encoded, live.
This means that when there is little sound to be heard, the encoder encodes the MP3 with a low bit rate as low as 16 kbps or less , but when there is very complex sound to be heard, the encoder uses a much higher bit rate up to kbps to attain better sound reproduction.

I'm not saying I don't believe it I'm keeping an open mind despite the fact I use kbps MP3 , just make your case a bit more effectively. If you think this forum is obsessive, check out HA.

The bit rate of a coded audio file is the number of bits binary digits - 0s or 1s - bits of digital information that are required to store 1 second of audio.
An mp3 at kbps requires , ish! The point of psychoacoustic coding is that you only store the audible part, but just how much information is needed to represent the audible part varies from 1 moment to the next. Silence doesn't contain very much information at all - rather than storing thousands of zeros, you could just store a code meaning "so many seconds of silence".
A Variable bitrate coder will vary the bit rate, depending on how much information is needed to store the audible part of a signal from moment to moment. If a decoder expects the same number of bits every second, this can really confuse it! A valid mp3 decoder must handle variable bitrate files. This was specified in the original standards document in
