The sum/difference mode can be used together with
the quasi-peak detector to determine the sound mate-
rial mode. If the difference signal on channel B (right)
is near to zero, and the sum signal on channel A (left)
is high, the incoming audio signal is mono. If there is a
significant level on the difference signal, the incoming
audio is stereo.
