NOTE: A secondary effect of mic-to-source distance is the extent to
which environmental ambience is picked up by a mic. For example, as a
mic is moved away from the source, the proximity effect decreases, but
the amount of “room tone” increases (assuming that you are not in an
anechoic chamber). The AVP does not model this effect. However,
judicious use of the Proximity control in combination with some appro-
priately programmed reverb will allow you to create the same effect,
with the additional bonus of being able to control the exact nature of
the room tone.
Tube Warmth Page
Tube Warmth Amount:
10.0.
The Tube section is designed to model the distortion that is typical of a
high-quality tube pre-amp.
When tube pre-amps are operated in their linear range, there is virtually
no signal distortion and their audio qualities are essentially identical to
solid state pre-amps. However, it commonly occurs that transients exceed
the linear voltage range, resulting in distortion. The distortion characteris-
tics of a vacuum tube pre-amp is vastly different than that of solid state
amplifiers and is often described as adding a certain “warmth” to a sound
(in contrast to what is often described as the “brittleness” of the solid
state sound).
The amount of tube saturation effect applied to your audio is controlled
by the Tube Warmth Amount control in combination with the Input Level
control.
The Warmth Amount control determines the amplification factor of the
modeled tube pre-amp with the numeric display indicating the amplifica-
tion in dB. At .0, no distortion occurs, even for full amplitude (+1 or -1)
signal levels. These levels represent the “rails” of the amplifier. As the
Warmth Amount is increased, the amplification is increased. Any regions
of the signal that increases beyond the rails generate distortion. (But
instead of the usual ugly digital clipping, they are distorted the same way
the tube pre-amp would distort the sound.)
