Ambience
The Programs:
Ambience
Ambience generates the appropriate early reflections for stereo simulation
of one of six different halls — one rectangular hall and one fan-shaped hall
in small, medium and large sizes — and sends the reflections to the side and
rear speakers. For systems with only two loudspeakers, Ambience also
incorporates a version of Panorama that will spread the stereo image and
add the reflections it generates to the expanded sound stage.
The initial EFFECT LEVEL is highest for Program 4 and progressively lower
for Programs 5 and 6. It will be easier to hear exactly what the parameters
do if the effect level is temporarily turned all the way up.
The LIVENESS parameter adjusts the amount of recirculation within the
program. The higher the value, the more reflective the surfaces of the
simulated space and the longer the sound will take to decay. At very high
values the decay is audibly less smooth than in the Reverb programs, which
are more effective at simulating very live spaces. Liveness
ROOM SHAPE selects one of two basic hall shapes. Refer to Chapter 5:
Theory and Design, for a discussion of the properties of the two. Room Shape
EFFECT LEVEL adjusts the loudness of the side and rear speakers. When
there are no side speakers, it adjusts the amount of ambient signal mixed
into the main loudspeakers. EFFECT LEVEL is the most important user
adjustment in AMBIENCE and REVERB, and has been given its own button
on the remote. It should be adjusted as high as possible without making the
extra speakers individually audible. Effect Level
