REVERB PARAMETERS:

Delay: Sets the amount of delay that occurs before the reverberator (called predelay). It can be adjusted from 0 to
255 milliseconds in 1-millisecond steps. Predelay is primarily used to maintain intelligibility by moving the
start time of the reverberant sound in relation to the dry signal. Typical predelay values are from 0 to 35
milliseconds. Increasing the predelay adds apparent depth to the image, up to the point where it becomes
an obvious slap delay/reverb effect at 255 milliseconds.
Size: Sets the overall size of the reverberant space, from 5 to 50 meters. This single control affects multiple
components of the algorithm and should be adjusted first when building a totally new reverb sound. It also
has a greater effect on the perceived acoustic space than any other parameter.
Large Size settings create bigger spaces, longer delays between reflections, lower running echo density,
and lower tonal coloration. Small Size settings simulate tighter spaces that are smooth with a high echo
density. Small Sizes should only be used in conjunction with short decay time settings or they may sound
tonal or metallic. When building a new sound, a value of 25 is a good starting point.
With the Gated class, Size is used to set the length of the gated reverb, from 50 to 500 milliseconds.
Regen: Controls the reverb's diffusion (initial echo density and the rate at which echo density builds over time).
The range of Diffusion is from 0 to 10, with 8 working well for most material. A low setting has little initial
density and a slow density build. Low settings improve clarity and openness on vocals and piano tracks. At
a setting of 10, the reverb starts with a relatively dense sound that almost immediately builds to maximum
density. Higher settings are usually the best choice with percussive material.
Decay: Sets the reverberation decay time from .3 to 28 seconds. Reverberation time is usually qualified as the
time it takes the reverberated sound to drop 60 dB in level. Depending on the chosen class, the sound's
bass and treble components may have different decay rates. Typical Decay values range from
approximately 1 to 3 seconds. Shorter decays allow for "vocal ambience" treatments. Longer decays
(greater than 3 seconds) are usually used for "bigger than life" special effects. Both the Decay and Size
parameters should be used together to set the overall impression of the simulated space.
