UNVEIL
t/ƒ LOCALIZE
t[REFRACT]
This parameter determines pattern localization along the
time and frequency axes. Higher values resolve individual
frequencies better but might introduce high frequency
oscillations that can sound artificial when a lot of noise is
present within the signal. Lower values reduce this type of
artifacts but might cause signal amplitude modulation
("pumping") that results from the process affecting not only
the detected patterns, but their surrounding sounds as well.
A value around the center position is usually the preferred
setting. If both low and high values do not produce
satisfactory results, we recommend you set it to its center
position, set FOCUS to center as well and change FOCUS
using the FOCUS BIAS sliders for critical frequencies only.
That way you will be able to separate reverb without applying
the process to the entire signal at once.
As an analogy, think of this as the “number of bands” - less
bands mean less control but less artifacts, more bands give
more control but more potential for artifacts.
t[REFRACT] determines the refractory time for the analysis
network, or “how long the algorithm thinks about what it has
heard before reacting”. Shorter values will cause the analysis
to be more sensitive to signal changes, but might affect short
term oscillations such as noise in a way that sounds artificial.
If you increase the refractory time, the overall sound of the
de-reverberated signal usually improves, but some of the
reverb reflections might return. We recommend you start out
at a zero value and increase as needed.
