the signal normally sent to the sides will be mixed into the front outputs.)

speech from other inputs. Essentially, this control turns down the effect to
make speech clearer. Whenever stereo signals are present, the right and left
input channels are used independently as inputs to the ambience synthesis.
If there is a strong monaural speaking voice present at the same time, this
component of the input to the Ambience algorithm is reduced while the
stereo component is increased.
If the input signal is pure monaural speech the input is almost entirely
attenuated. SPEECH DETECT is a real benefit to some popular music
(where spoken voice, such as rap, occurs along with music), stereo televi-
sion, and early stereo movies. Any stereo material which was not carefully
