I can recall playing a very warped bit of mono vinyl, and if you did switch
from stereo to mono you could hear the changes in phase presumably.

Are we saying then, that some mono recordings are cut in stereo and that the
engineering is such that they can get the balance badly wrong?
I suppose this could occur where stereo and mono tracks are being cut on the
same disc. However it gets even worse as it was of course a regular practice
in the bad old days to 'synthesize the stero using echo, delays, phase and
tone changes.

OK, pending my marching orders from Arny (or anybody else, come to that)
I've got another 'dual mono' question to ask:

This don't look right to me:

Is it dual mono? Is it possible to tell by just looking at the waveform?




They are similar but not identical, the bottom channel looks as if it is
has a lower db recording signature...Stereo/ dual mono???
