REVERB-1 algorithms are best used when you are using multiple effects. They have
less density and are more suited to effects where the reverb is not the main
effect but is used for presence.
REVERB-2 algorithms use more delay and have a higher complexity than the REVERB-
1. REVERB-3 algorithms are the most complex and dense. Always use REVERB-3 when
building "reverb only" programs.
The TYPEs of reverb are what make up the reverberant space. The smallest space is
the Plate. Generally this reverberant sound is used for tight and harsh sounding
reverb. Room and Vocal types are the next size spaces. They tend to be a little
looser allowing the sound to "bounce" around more adding color to the sound. The
Hall types are the largest allowing you to fill in the spaces with reflections
and build up density.
Once you decide what type of space is required, the length of DECAY is selected.
Generally the size of the space is proportional to the time it takes the signal
to decay. The larger the space, the longer the decay. Don't stick to this rule!
Many quality sounds are made by bending the rules and allowing for creativity.
Since reverberant spaces tend to boost high frequencies the High Frequency
Damping (HFDAMP) parameter allows you to damp out frequencies as natural damping
would in a reverberant space. Putting up baffles, carpeting, drapes or wood in
the space is simulated. The higher the value, the more damping.
Position (POSITN) puts you as a listener where you would hear the sound if you
were in the space. Front positions you closest to the initial signal so you here
more 1st reflections and the reverberant decay is in the background. As you
position yourself more towards the Rear, you "mix" the initial sound to
reverberant sound ratio. At the Rear of the space, you hear the signal decay with
all the reflections and very little initial sound.
Diffusion (DIFFUS) is how much the sound bounces around in the space. The lower
diffusion % is looser and the smoothest at 100%.
LEVEL adjusts the effect level of the preset.
