The Chamber effect produces
an even, relatively dimensionless
reverberation, with little change in
color as the sound decays. The
initial diffusion is similar to the Hall
effect, but the sense of space and
size is much less obvious. This
characteristic, along with the low
color of the decay tail makes Cham-
ber useful on a wide range of ma-
terial. It is especially useful on spo-
ken voice, giving a noticeable in-
crease in loudness with very low
color.

Sustain of reverberation after initial build up
The Hall effect emulates a real
concert hall. The reverberation is
very clean, and designed to re-
main behind the direct sound —
adding ambience, but leaving the
source unchanged. This effect has
a relatively low initial density which
builds up gradually over time.

The MPX 1 Reverb effects provide a full suite of reverberation and ambience algorithms.
All of the reverbs are true stereo in that differerent processing is applied to the left and
right input signals. Dedicated processing resources are allocated to the reverb effects
so that you can always load any reverb into any program, regardless of what other effects
are loaded.
