Originally posted by verloren Where you can get variations in size is with VBR (variable bit rate) encoding.

Most encodes will be between 640 and 1288 over intended bitrate. This is consistent to all bitrates by the same encoder.
That's all I know for simple observations. Perhaps someone else has the real answer. Another odd side effect appears in Winamp. The main display shows a bitrate which appears to be a figure rounded down and then subtracted 1. Such that a file as 128,640 appears at 127 and a file at 129,288 would read 128. Odd....Leave it MS, I guess.
