Over the time of the blog i’ve continually improved the decoding process’s for the various matrix systems that were used by record company’s to encode four channels onto a stereo LP.
I’m now at a point where i feel that there is very little improvement that can be made using the tools we have at hand at this time, so many of the process’s are being upgraded to include my recent work on solving the individual issues of each system that were not possible to deal with, or talked about, in the 1970’s and will be the end to my research and development of such process’s.
To distinguish these from all previous process’s they are named after ‘mythical’ creatures:
Matrix H: ‘Hydra’
Matrix HJ: TBA
The following process’s remain the same:
Dolby Surround: DS/IV
