>From my understanding, vorbis peeling would work somewhat like Mp3PRO. What
they created was a file with a 64kbps size, but a near-128kbps quality. If you
decoded the mp3 using a standard mp3 decoder, you got the 64kbps quality, but if
you used an mp3-pro decoder, it would display as 128kbps and mp3pro, and there
would be added quality to it. It seems the format worked by having 2 streams
layered within the file, and one stream was just 64kbps, and the second stream
could be utilized by a special decoder that would then add the second stream to
the first, increasing the sound quality.
Would it be possible to have the encoder do the following: it would create a
quality 1 stream. Then it would create a quality 2 stream. check the
differences between the streams. Subtract stream-quality-1 from
stream-quality-2, and find out what is left. This new stream would consist of
''what you would add to
stream-quality-1-to-make-it-sound-near-quality-2''. Do the same with
quality 3, 4, 5, up to the highest quality you want.

Then the decoder would play the layers together, 1+2+3 for a near-quality 3
file.
I have no programming knowledge at all, except for (X)HTML and CSS. Just some
brainstorming.
