output level.
Filter Amount This setting controls the degree to which the ASIF can affect the signal,
with 0% corresponding to no filtering and 100% corresponding to full
filtering. In general, it is best to use the minimum Filter Amount setting
that produces the desired result. When Equalize Voice mode is used, a
lower Filter Amount can reduce artifacts that result from a fast adapt
rate, so the Filter Amount can be used to help strike a balance between
responsiveness and stability. When Attack Noise mode is used to reduce
bandlimited noise, a lower Filter Amount setting will often be a better
choice to prevent the elevation of background noises.
Note: Changing the Filter Amount setting does not require an
adaptation period to arrive at a “good” solution. Because a full average
spectrum is maintained regardless of the setting, the new filter amount
setting takes effect instantaneously in both the output audio and the
display traces. However, since the auto gain adapts based on the actual
applied filter with filter amount taken into account, there may be some
adaptation time required to reach a stable auto gain value after the filter
amount is adjusted.
Example 2 below illustrates the effect of the Filter Amount control.
Output Gain and
Auto Gain:
These controls provide two options for adjusting the level of the ASIF
output. When Auto Gain is enabled, the ASIF automatically monitors
the input and output levels and applies a gain value that matches the
output level to the input level. When Auto Gain is disabled, the user can
use the Output Gain setting to specify the amount of boost applied to
the ASIF output.
The Auto Gain is an adaptive value whose rate of change depends on the
same Adapt Rate slider setting that controls filter coefficient averaging.
This means that when the filter response changes rapidly and
dramatically, the auto gain will take some time to “catch up” to these
changes. In particular, the output audio may clip when user settings are
changed in a ways that have a boosting effect, such as switching from a
pink to a flat shaping curve, adjusting the filter amount, or increasing the
size of the ASIF region in Equalize Voice mode so that some frequencies
that had been heavily attenuated are now present. While these settings
changes will take effect immediately, the Auto Gain may take some time
to adapt to the change. For this reason, when the user expects to be
making many changes in the settings, it is often better to disable Auto
Gain and instead choose a manual gain setting that avoids clipping.
Lower and Upper
The Lower and Upper Voice Limits allow the user to specify the
