This is a long post, so those not interested can ignore it.

This brief history is not exhaustive, and covers mostly surround sound as
applied to records. There were separate developments for broadcasting, and
these have been mentioned in passing, but not covered in detail. I have
also not discussed Ambisonics in any detail.


I would have thought any history of surround sound for recording would
contain more than a passing mention of Ambisonics. It seems to me like the
Betamax of surround sound - technically superior but poorly marketed.
