Ambience Control
Use the ambience function for boom boxes, head-
phones, desktop speakers, or other audio products
where the speakers are physically close together. A
stereo signal is designed to be played over speakers
that have a wide physical separation. The ears and
brain combine the sound from these two sources to
create a perception of sounds distributed in space. In
the case of headphones, this wide physical separation
does not exist, resulting in the sound apparently com-
ing from somewhere inside the head. A similar situation
exists when the speakers are not widely separated, for
example when they are located on a desk or inside a
single enclosure. One way to compensate for this is to
increase the apparent separation of the L and R signals
arithmetically. The L and R signals can be modeled as
a channel-specific component added to a monocompo-
nent. To emphasize the channel-specific component,
one needs to remove the opposite channel-specific
component from the monocomponent.
This function is accomplished with circuitry inside the
MAX5406 and external network. Control the ambience
effect with the
AMB
button that toggles between wide
(full effect) and normal (no ambience effect). Use the fol-
lowing equations for matrix surround (fixed ambience):
