Reverb

Reverb uses reflections of sound to add depth and fullness; the sound will seem to come from a space that can go from a small bare room to large natural valleys, cathedrals, etc. The reverb is made up of a group of echoes that occur at the same time making it feel like a single effect. Basically simulates creation of a large number of reflections, like lots of walls, which build up and then decay. You can use the reverb plugin to mix tracks together to simulate ambiance because it is a multitrack effect. The configuration window (figure 10.20GUI of configuration for Reverb plugin) shows a graph of the full band pass filter frequencies.

Initial signal level
(db): Allows you to set the level of the reflected signal. At 0 you start from its maximum level. Decreasing the signal volume will give more presence to the original signal.
ms before reflections
: indicates when to start the reflected sounds in relation to the original sound (delay).
First reflection level
(db): the sound level of the reflection that starts first.
Last reflection leve
(db): the level of the last reflection. It is weaker than the first.
numbers of refelctions
: the number of reflections can be set as desired as long as there is sufficient CPU to handle it. With a few reflections you get closer to the Chorus effect. You can start from values of 100 - 150, up to a maximum of 255.
ms of refelction
: Sets the action time of the effect. With high values, the sound is more clear and sharp
Low freq of bandpass
and High freq of bandpass: allow you to set the frequency limits (range) on which the effect acts.
Steepness of bandpass
: allows you to adjust the slope of the frequency range limits imposed by the previous items. With the value 1.00 we have a vertical edge that clearly separates the range of frequencies on which to act from the remaining ones (as you can see in figure 10.20GUI of configuration for Reverb plugin). By sloping the edge we have a certain overlap and a smoother effect.
Window
: determines the number of frequency samples taken into account by the effect for its calculations. The higher the number, the smoother the effect; but more CPU is used.
