The
Dynamics effect provides a set of controls that can be combined
or used independently to adjust audio. Use either the graphical
controls in the Custom Setup view, or adjust values in the Individual
Parameters view. This effect is available for 5.1, stereo, or mono
clips.
- AutoGate
-
Cuts off a signal when the level falls below the specified
threshold. Use this control to remove unwanted background signals
in recordings, such as a background signal in a voice-over. Set
the gate to close whenever the speaker stops, thereby removing all
other sounds. The LED display colors indicate the gate’s mode: open
(green), attack or release (yellow), and closed (red). Use the following
controls for Gate:
- Threshold
-
Specifies the level (between –60 and 0 dB) that the incoming
signal must exceed to open the gate. If the signal level falls below
this level, the gate closes, muting the incoming signal.
- Attack
-
Specifies the time the gate takes to open after the signal
level exceeds the threshold.
- Release
-
Sets the time (between 50 and 500 milliseconds) the gate
takes to close after the signal level has fallen below the threshold.
- Hold
-
Specifies the time (between 0.1 and 1000 milliseconds) the
gate stays open after the level has fallen below the threshold.
- Compressor
-
Balances the dynamic range to create a consistent level throughout
the duration of the clip by increasing the level of soft sounds
and decreasing the level of loud sounds. Use the following controls
for Compressor:
- Threshold
-
Sets the level (between –60 and 0 dB) that the signal must
exceed to invoke compression. Levels that fall below the threshold
are unaffected.
- Ratio
-
Sets the ratio by which compression is applied, up to 8:1.
For example, if the ratio is 5:1, and the input level increases
by 5 dB, the output increases by only 1 dB.
- Attack
-
Sets the time (between 0.1 and 100 milliseconds) that the
compressor takes to respond to a signal that exceeds the threshold.
- Release
-
Specifies the time (between 10 and 500 milliseconds) it takes
for the gain to return to the original level when the signal falls
below the threshold.
- Auto
-
Calculates the release time based on the incoming signal.
- MakeUp
-
Adjusts the compressor’s output level (between –6 and 0 dB)
to account for loss in gain caused by compression.
- Expander
-
Reduces all signals below the specified threshold to the
set ratio. The result is similar to the gate control but is more
subtle. Use the following controls with Expander:
- Threshold
-
Specifies a level in which the signal must fall to activate
the expander. Levels that exceed the threshold are unaffected.
- Ratio
-
Sets the rate at which signals are expanded, up to 5:1. For
example, if the ratio is 5:1, a level decrease of 1 dB is expanded
by 5 dB, resulting in a much faster decrease of the signal.
- Limiter
-
Reduces clipping in audio clips that contain peaks in the
signal. For example, by leveling out peaks that exceed 0 dB in an
audio file, the overall level of the audio doesn’t have to be reduced
below 0 dB to avoid clipping. Use the following controls with Limiter:
- Threshold
-
Specifies the maximum level of the signal, between –12 and
0 dB. All signals that exceed the threshold are reduced to the same
level as the threshold.
- Release
-
Specifies the time (between 10 and 500 milliseconds) required
for the gain to return to the normal level after a clip occurs.
- SoftClip
-
Reduces clipping similar to Limiter but doesn’t use hard
limiting. This control adds an edge to some signals to better define
them within an overall mix.
