May not qualify to be in this thread, but I just happened to find this: a Dolby Surround encoded music video.
The DS encoding seems to survive whatever audio data reduction system YouTube uses.
IIRC, Shure believed that (stereo) music videos could be a "backdoor" for surround sound to be reintroduced (hopefully using the Shure matrix encoding/decoding system).
'Thriller' was also Dolby Surround as were some MV from the British group 'ABC'
Now that is cool, that they printed "quad compatible" on the cassette and artwork. Have you ever been able to compare it
Not as good as the lp , but not that bad really. There were only a small number of Companies that had quad matrix cassettes.Now that is cool, that they printed "quad compatible" on the cassette and artwork. Have you ever been able to compare it against the quad LP and see if the decode is better or worse fizzywiggs?
CBS had there single inventory ones, BASF had some , and A
I used to listen to a lot of SQ and RM encodes from CD-4 on cassette , but it was my encoding to cassette and my playback on the same machine. They were much better for quad matrix listening .
Besides that I had ( and still have some) BBC matrix quad on cassette that sounded quite good when decoded on playback .
I think it depends on how you fold the liner notes when you put it back in the case. From memory, they all have that Tomita in Surround as one pane of the liner notes
Aha!not much on the spine.
