I've recently noticed that after editing tags with MP3Tag, there will be a long period of silence added to the end of the MP3 files, often with a loud noise near the beginning of it as well. VLC Media Player seems to skip the long silence after a couple of seconds, so I only recently noticed it was happening. Opening the MP3 file in an editor and deleting the noise/silence doesn't effect the tags at all, so apparently the two aren't connected.
So far, the problem seems to be limited to MP3 files. It's never happened when using WAV files and I don't think it happens with FLAC, either. Has anyone else noticed this?
