1K Club - QQ Shooting Star
- Jul 5, 2010
Often the art of audio design is mentioned. But in the case of matrix surround I think your "black art" is most appropriate. In fact I think Severus Snape had something to do with the SQ system.
Yep. If it tests good but sounds bad your testing the wrong thing. Still testing is a required part. I guess the point is your ears & the testing should agree.
The basic QS/RM Vario-Matrix is just a great concept for quad or stereo & much of it's "sonic signature" depends on how it's implemented.
In another post I think you commented on how stereo to surround seems like magic (the good kind) to you. Discrete SACD, DVD-A, you just expect to work. But S2S can be a real surprise & I totally agree. My 1st encounter with surround sound was a stereo record (Switched on Bach) played through an ultra-simple 3rd speaker L-R hook up. I was blown away. And I've have that same appreciation today.
Actually, the heads of Columbia Records stuck their uninformed minds into SQ with a coporate directive:
They directed that any Columbia matrix system must preserve full left-front-to-right-front separation in both stereo and quad play.
Only a few systems have that property:
- Dynaco diamond
- Dolby Surround
I have always used the Poincare sphere to test matrix design and calculate the effects of stereo transforms such as S2S. So I am rarely surprised by what actually happens when a technique is used.
