Of all the mp3 files from various encoders that I have encountered, LAME is the only encoder that seems to encode beginning silence in a way that combines it with the audible portion so that it cannot be removed. Some of the files have nearly a second of silence, which can be very noticeable and annoying. Attempts to remove this silence by removing frames from the beginning of the file corrupt the audible portion so that a chirp or squawk is usually produced. Encoding beginning silence in separate frames would allow it to be trimmed by users who find it problematic. (This characteristic may apply more to VBR encodings than CBR.)
