"Unsychronization scheme" is a compatibility feature for older software that does not understand id3 tags and looks for MP3 synchronization frames (certain sequences of adjacent 1-bits) to find out where the actual stream starts. This scheme is a simple escaping for such sync frames that may occur in tags and hence fail id3-unaware software. I don't have any files that use this scheme, so I did not bother to implement it. I also thought that maybe we can do without it...but now it looks like we can't. Implementation is not difficult to do, the only problem is that I don't have any test data readily available. But it shouldn't be too hard to find some. Thanks for your efforts. Petteri
