Hi,

a simplified explanation for this phenomenon.

One of my microphones is a Rode NT4, a "Stereo microphone with
90 ° X / Y stereo array". Even with headphones on, some of those stereo
recordings appear as if they are mono recordings. If you pan the two
channels from left and right to the center you will notice the
difference. A stereo recording, that appears as if it is a mono
recording does sound way livelier, with the two channels separated to
full left and right. The reason for this type of stereo recording is,
that if both channels are panned to the center, so that the two signals
become a single mono signal, it doesn't cause much phase problems. IOW
such a 90 ° X / Y stereo array recording is a mono compatible stereo
recording and can be played by a stereo system, as well as a small mono
radio. Very noticeable widely spread stereo signals sound interesting in
stereo, but usually sound muddy in mono. Parts of the signal could be
completely missing due to phase cancellation.

Here somebody demonstrates phase cancellation. What he says about
microphones is incomplete. This effect does usually not happen that
noticeable, when recording with a 90 ° X / Y stereo array:

Instead of using the 90 ° X / Y stereo array, another way to do a mono
compatible stereo recording is to record the middle and just one side,
but that is a topic in itself.

In a nutshell. You can usually no longer listen to clearly perceptible
stereo recordings on the mono radio, which is why professionals often
make subtle stereo recordings. Less is more!

Ralf
