Reference

Reverb Level

Reverb Level sets the amount of reverberation in the processed signal. It is normally FULL, but may
be reduced for effects where the pre-echoes should dominate.

Reflect Delays

In the Chamber and Inverse algorithms, L Refl and R Refl provide pre-echoes to the left and right
channels. In Chamber, the maximum delay value is 1.2 seconds. In Inverse, the maximum delay value
is 800 milliseconds.

Reflect Levels

L RefLvl and R RefLvl control the level of the reflections (L Refl and R Refl). The range of each level
is from Full (0dB) to -85dB, and to Off.

Shape, Spread

Shape and Spread work together to control the overall ambience of the reverberation. Shape
determines the contour of the reverberation envelope. With Shape all the way down, reverberation
builds explosively, and decays quickly. As Shape is advanced, reverberation builds up more slowly
and sustains for the time set by the Spread. With Shape in the middle, the build-up and sustain of the
reverberation envelope emulates a large concert hall (assuming that Spread is at least halfway up,
and that Size is 30 meters or larger). Low Spread settings result in a rapid onset of reverberation at
the beginning of the envelope, with little or no sustain. Higher settings spread out both the buildup and
sustain.

Size

Size sets the rate of build-up of diffusion after the initial period (which is controlled by Diffusion). The
Size control changes a reverb sound from very large to very small. Generally, you should set this
control to approximate the size of the acoustic space you are trying to create, before adjusting
anything else. The size in meters is roughly equal to the longest dimension of the space. Audio is
temporarily muted when Size is changed.
