I always understood that variable encoding uses an algorithm to determine the required bitrate for specific sorts of audio output, and varies the size of each sample according to that data. If you want a more exact copy of your audio file: if, for example, you are editing music, , I would not choose this method. However, for most things it'll probably be fine.

VBR with joint stereo will usually give a better trade-off between file size and sound quality than other combinations.The "Preset" options are generally a very good choice for music recordings.Some MP3 players will report the duration of tracks incorrectly for VBR encoded MP3s, though virtually all MP3 players will be able to play both VBR and CBR correctly. CBR is able to provide smaller file size than VBR by selecting a very low bit-rate but the sound quality will be very poor.
