I'm working my way through the BBC Technical Delivery Standards, and I came across this specification:
If mono originated sound is used, it must be recorded as dual mono, so that it may be handled exactly as stereo. It must meet all the stereo standards regarding levels, balance and phase.
As far as I understand it, 'recorded as dual mono' means that a signal from a single microphone would be fed into two channels of a recorder, set as stereo linked. Is that correct?
If so, I fail to see the point of such an exercise, or what is meant by 'so that it may be handled exactly as stereo'.
Can someone with experience in these matters please enlighten me?
