Keep in mind that the ISO documentation is required since the format is going to be some kind of standard. But the companies writing it are surely *not* trying to make it easy for other people to impliment a good encoder, and I'm sure they leave out as much as possible. So if something in the ISO docs does (like the completely broken M/S stereo "sparsing") not make sense, try other strategies. Tonality estimation is another good example - the default tonality estimater in the FhG mp3 encoder is not what is given in the ISO docs. If you do experiment with other algorithms and find something that works well, I hope you'll share your experiences with this list.
