The author of this page clearly has a bone to pick with some of the MP3 decoders out there. From the site: This site contains test results on a number of mp3 decoders. Such a test wouldn’t be necessary if all decoders worked properly, but unfortunately they don’t. In fact the outputs of many popular decoders were found to be incorrect. .
