Space
In some sense, Shape determines the spatial characteristics of the reverberator,
whereas Materials effects the spectral characteristics.
Preset Design Tips
Here are some practical tips for creating useful reverbs with DreamVerb.
These are not rules of course, but techniques that can be helpful in designing
the perfect sonic environment.
ER = Early Reflections
LF = Late-field Reverberation
Hf = High frequency
Lf = Low frequency
General Tips (a tour):
• Start by setting a general timing on the ER and LF graphs to give a rough reverb
size. This timing ordinarily needs to be tweaked several times along
the way.
• The materials and air density define the frequency decay of the LF, and also
the coloration of the ER if ER filtering is used (the slider on the right of the Reflections
panel).
• Typically, materials should be blended. Try blending contrasting high frequency
roll-off materials with high-frequency reflecting materials or inverse
materials. This tends to add nice dimension to the LF tail. Start with one useful
material and experiment with blending.
• Materials can have an extreme filtering effect if no air density is used. Most
presets sound better with an air blending. If you don't want the additional
coloration of air, blend with “Ideal Gas” which performs no filtering.
• The room shapes define the ER pattern; they do not effect the LF. Solo the ER
and choose a shape that works well for your source or environment.
• Blending shapes does not always yield desirable results. Use shape blending
with discretion, or to define a more complex room.
• Start with the EQ flat, set the approximate sound with the materials, then EQ
the input to cut or boost specific frequencies.
• The EQ is often most useful for a simple Lf or Hf roll-off/boost, or to notch out
bothersome frequencies for particular sources. For full mix ambience/mastering
presets, use the EQ to cut most of all LF input, which yields added ambience
without mucking up the mix. This is a powerful EQ, so experiment!
