Flawn,

Thanks for the compliment in your email.

I'm writing a guide to field recording in stereo and trying to explain
various effects in less technical language with demonstrations. One is
random noise with a L-R shift of 5 samples or just over 1 millisecond
or a distance shift of 38mm (1 1/2 inches).

This gives a stereo shift to about one sonel (sound pixel) on a 9
sonel stereo image which is how I measure stereo image placement. The
basic sonel points are left - mid - centre and if you keep filling in
the gaps, you get to 9 sonels if you are lucky. :-)

Hope I haven't lost you. :-)

Sorry, my mistake. It's BBC terminology for "Blumlein" who
experimented with spaced mono mics. I forgot it was also used for
coincident pair setups.

For "Blumlein" please read "separated pair" and this also applied to a
dummy head binaural pair.
