[BC] The real thing....

[RichardBJohnson at comcast.net]

For other readers of this thread:
Blumlein is generally regarded as the inventor of stereo.
Some of his contributions are:

The use of a coincident pair of velocity microphones with
their axes at right angles to each other, which is still
known as a "Blumlein Pair."

Recording two channels in the single groove of a
record using the two groove walls at right angles
to each other and 45 degrees to the vertical.

..basically recorded just as it was obtained.

Some consider him the greatest inventor of all
time.
