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 Specifiesalevelinwhichthesignalmustfalltoactivatetheexpander.Levelsthatexceedthethreshold
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.
EQ effect
The EQ effect acts as a parametric equalizer, meaning that it controls frequency, bandwidth, and level using multiple
bands. The effect includes three fully parametric mid bands, a high band, and a low band. The low and high bands
areshelvingfilters,bydefault.Gainisconstantoverfrequency.TheCutcontrolswitchesthelowandhighbandfrom
shelving to cutoff filters. Gain is fixed to –12 dB per octave and is deactivated in cutoff mode.
Use the graphical controls in the Custom Setup view, or adjust values in the Individual Parameters view. In the
Custom Setup view, you can control the parameters of the filter bands in the Frequency window by dragging band
handles. Each band includes a control for Frequency and Gain. Mid bands include two additional controls for
adjusting the Q-factor. This effect is available for 5.1, stereo, or mono clips.
The EQ effect has the following settings:
Frequency Specifies the amount by which to increase or decrease the band (between 20 and 2000 Hz).
