Good question, and a very good reason for another of my long-winded dire-tripe’s…..
After working on what became DS/IV (for Dolby Surround) i decided to utilizes the new process for it’s big brother SQ. Although SQ/III was perfectly ok, as i stated there could only be an SQ/IV if an improved way of performing the logic/expansion function, and as the new process worked so well for Dolby Surround it was obvious to try it on SQ.
So work started but it soon became obvious that there were some serious issues that had to be overcome and the problem lay in the lack of powerful enough tools to perform the process without causing any damage to the wanted information. So after a great deal of work SQ/IV was shelved indefinitely. Not one to give up on a good idea, the next day i started work on a hybrid process using SQ/III and IV which started to show good results.
Finally, after the usual testing and re-testing (thanks Owen for help in the final test) what i ended up with was a process that actually performed almost as well as IV but without any of the issues. In fact the differences are quite small and not even worth mentioning as i suspect nobody would be able to tell the two apart (if IV was possible) performance wise.
So out of the ashes of failure springs new life, and it’s called ‘SQ/Phoenix‘.
So what’s the difference? The only area of SQ that has remained a problem since it’s inception is the front channels. They still contain all of the rear channel information. Although i had made some inroads into reducing this throughout the II & III series there was still enough left over to reduce the Front to Rear separation and blur images. It is also the one major thing that stops SQ being considered as ‘discrete’. Until now.
Comparing Phoenix with CD-4 i believe it is fair say say this is the first time that discrete SQ decoding is possible. A brave statement i know, and one i do not make lightly, those who know me know i’ve never used that word publicly to describe any of the matrix decoding process’s. And to those who love to try and take me down, and yes i know this will get to you, best take your best shot, i’m ready for you!!!
So tomorrow will be the first release using ‘Phoenix’, so it would be nice to have some feedback, positive or negative. Oh and you may find at first that there’s something wrong. just remember all there coming from the fronts now is just the fronts, the rears are behind you.
Oh and please don’t ask about re-issues (although over time it will happen), this has been a long hard slog, i need some rest and also need to get to releasing new material…….
