[vorbis-dev] Idea for gapless tracks

We all know that currently Vorbis is the only codec out there that
doesn't add any silence to the decoded file, so when you decode
your .ogg file the resulting .wav will be exactly the same length
as the original one. This is very useful when encoding gapless
songs (like live concerts...). But since Vorbis is a lossy codec,
even though there is no silence added, sometimes you can
still hear a click between gapless tracks because the end of
the first song doesn't match up with the beginning of the second
song. This doesn't happen always and as you encode files using
higher bitrates these clicks seem to appear less frequently
One of the solution would be to "teach" the encoder that
it has to pay attention that the end of one songs should
match up with the beginning of another one. But I'm
thinking that there might be a better solution: the encoder
shouldn't use psycho-acoustic at the very begging &
very end of the songs (for a few milli seconds). This will
ensure that the edges will always match...
Does this holds water or not?
