A Proposal for the High-Quality Audio Application of High-Density CD Carriers

http://www.meridian.co.uk/ara/araconta.htm

Some interesting ideas.

Quote:
This document has been prepared as a serious proposal to all concerned in the future of high-density CD formats applied to pure audio.

Its authors present here some consensus views and arguments leading to three important outcomes.

The first is a proposal for a new data type for the compression layer in the MPEG system stream encoded on the high-density discs. This data type carries losslessly compressed linear PCM (packed) audio, and is quite distinct from the currently recognised streams carrying lossy-compressed (data-reduced) channels such as MUSICAM, MPEG Audio, PASC or AC-3.

The second is a working proposal for a disc format, which in its essentials is:

That lossy data-reduction techniques such as MUSICAM, MPEG Audio, PASC or AC-3 should not be used in any form for the high-quality sound application.
That higher quality should be based on surround sound and use linear PCM with more channels and a higher data rate than current CD-DA.
That our proposal does not add significant cost to any currently proposed video players, and is structured in such a way that only the more advanced applications will require extra hardware.


And more..
