tape recordings. This effect is available for 5.1, stereo, or mono clip.
Specifies the level (in decibels) of the noise floor as the clip plays.
Stops the noise floor estimation at the current value. Use this control to locate noise that drops in and out of a clip.
Specifies the amount of noise to remove within a range of –20 to 0 dB.
Sets an offset value between the automatically detected noise floor and the value defined by the user. This is limited to a range between –
10 and +10 dB. Offset allows additional control when the automatic denoising is not sufficient.
Dynamics effect
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.
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:
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.
Specifies the time the gate takes to open after the signal level exceeds the threshold.
Sets the time (between 50 and 500 milliseconds) the gate takes to close after the signal level has fallen below the threshold.
Specifies the time (between 0.1 and 1000 milliseconds) the gate stays open after the level has fallen below the threshold.
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:
Sets the level (between –60 and 0 dB) that the signal must exceed to invoke compression. Levels that fall below the threshold
are unaffected.
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.
Sets the time (between 0.1 and 100 milliseconds) that the compressor takes to respond to a signal that exceeds the threshold.
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.
Calculates the release time based on the incoming signal.
Adjusts the compressor’s output level (between –6 and 0 dB) to account for loss in gain caused by compression.
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:
Specifies a level in which the signal must fall to activate the expander. Levels that exceed the threshold are unaffected.
