creates the typical “high frequency loss” that often
happens in natural echoes. A setting of 127 means that
the signal isn’t filtered, while lower settings filter the high
frequencies of the feedback signal.
Reverb
The Reverb effect is probably the most widely used effect
in music production. It is used to add a realistic ambience
to clean and dry audio recorded in a studio. Very
complicated mathematical algorithms are needed to
simulate the complexity of a natural reverb. As a result,
good reverb processors are very expensive. The Largo’s
reverb effects don’t intend to simulate the perfect natural
room, rather they are an addition to the Largo´s sound
synthesis to make it more 3 dimensional and expressive.
Predelay 0...127
Determines the delay in milliseconds between the direct
sound and the reverb effect output. A natural
reverb
contains a reflexion which is heard later than the original
signal. The predelay determines this
delay so that the
reverb is separated from the original sound. Lower settings
connect the reverb more
to the original signal while
higher settings separate the effect signal to produce a
more spatious sound.
Size 0...127
Determines the length of the longest room side in meters.
Lower settings simulate a normal room while higher
settings simulate a big hall or church.
Density 0...127
Controls the density or diffusion of the early reflections. In
real rooms, even the first echoes are smoothed out by the
surface and material of the walls. Recommended settings
are above center.
Shape 0...127
Controls the timing proportion of the early reflections to
the dimensions of the late reverb. Medium settings
roughly result in matching dimensions of the early
reflections to the late reverb. Smaller values change the
room to a tube or a reverb plate, bigger values increase
the dimensions to around twice the actual room size.
Diffusion 0...127
Determines the consistency of different room materials.
Lower settings produce a cold strong reflection like a
metal or tile wall. Higher settings make a warm and thick
