This site is dedicated to the quadraphonic albums that were released on vinyl LP during the 1970/80’s/90’s using the various Amplitude/Phase Amplitude Matrix systems (DY, EV-4/Stereo-4, CM, QM, QX, SQ, QS, BMX, Matrix H, System HJ) developed in Japan, the USA and the UK during the “heyday” of Quadrophony.
The albums are decoded using bespoke process’s based on the respective companies technical/patent information for the best, most accurate, quadraphonic experience ever from a matrix source.
A recent addition to the work undertaken is uncovering hidden quad mixes of TV & Film soundtracks under taken during the mix down for use as “Soundtrack Albums”. To date these have been found to have been encoded using the ‘original’ matrix system ‘DY’, apart from one that was ‘SQ’ encoded, most probably a planned soundtrack album that never happened.
There are no limitations to the styles of music covered here, literally anything that was released could appear, from the well known and popular rubbing shoulders with the rare and completely obscure.
You’ve been warned! 😉
There has been a change in how the decodes are made listening.Originally they were released on DVD ISO’s, but producing the disc images proved to be too time consuming when the time to produce the decode is also taken into consideration.
So now they are made available in the ‘5.1 Flac’ format, where the front centre and sub channels are silent. Depending on the source used the files will be either 24/48 or 24/96.

Can you send me the password to Alan Tew- Carnival?
You wrote that – password is wide eys open.
NVDA doesn’t read all words at a post, even highlighted.
Hugs from Brazil.
I read all posts and comments from your albums searching for this.

I think you don’t know what NVDA is…
This program reads the words in the screen for blind
people or people like me with 2 per cent of viewing.
If you don’t want to send me the password, patience…
I will not sleep under the sink because of it.
Thanks anyway…

Whatever NVDA is, it’s not very good if it can’t find it.

Always have time to understand a little…
Without NVDA, JAWS, Voice-Over or its equivalents, blind
people don’t use computers or phones.
Example:
all front covers from the albums you posted- none of that
screen reading programs tells you there’s a photo and
describe what is in it, just pass over and says the first word
in sequence.
All tecnology tends to leave blind people forgotten, out of common
contact with other sighted people, it’s a cruel kind of prejudice,
as if the “seeing people” were sure they would never go blind.
Each one with its cross…
At least, you read all the answer !

How can I write these flac files to DVD, please?

Directly you can’t. It depends on your systems abilities as to how you go ahead to create an audio DVD.
Best do a search of the internet once you know what your able to play.

Roon is music streaming system that handles multichannel nicely. In my fairly basic set-up I have digital files on external HDDs connected to an Intel NUC. The NUC acts as a dedicated Roon server and connects in turn to a multichannel streamer that drives 6 speakers in a 5.1 (or 4.0) setup. The Roon software offers a lot of control over the signal path and has a nice, clean interface. If you have a Tidal subscription you can link the two and then use Roon to play files in your own library, or files from Tidal’s library. And it links to metadata services to try to recognise your files and pull in track lists, reviews etc. I’m sure there are countless other ways to achieve the same end, this just happens to be the way I discovered when I got into digital (after years collecting vinyl and then CDs) a few years ago.

Many thanks for that. I don’t do ‘Streaming’ so that’s me out.
