Effects and transitions
Specifies the gender of the narrator or vocalist. This option helps the effect to adapt to the difference
Male and Female
in tone between genders.
DeHummer effect
The DeHummer effect removes unwanted 50 Hz / 60-Hz hum from the audio. This effect is available for 5.1, stereo,
or mono clip.
Specifies the amount of reduction to apply to the hum. High values may also cut necessary audio

information in the low end.
Specifies the center frequency of the hum. Usually this will be 50 Hz in Europe and Japan, and 60 in the US
Frequency
and Canada. Often the frequency of the hum is not static, but will vary by +/– 5 Hz. Click the 50 Hz or 60 Hz buttons
to set the respective frequency.
Specifies the number of filters to use to remove the hum. Hum is comprised not only of the fundamental
Filter
frequencies of 50 or 60 Hz, but also contain harmonics with frequencies that are multiples of the fundamental (100/110
Hz, 150/160 Hz, and such). Higher values cause greater CPU usage. Adjusting this value determines the number of
harmonic frequencies to filter. For example, if you choose 60 Hz as the Frequency value, and choose 4# as the Filter
value, the DeHummer filters the 60 Hz frequency along with three harmonic frequencies (120 Hz, 240 Hz, and 480
Hz), for a total of four frequencies filtered, hence the value of 4#. Higher values require more processing power.
Delay effect
The Delay effect adds an echo of the audio clip's sound that plays after a specified amount of time. This effect is
available for 5.1, stereo, or mono clip.
Specifies the amount of time before the echo plays. The maximum is 2 seconds.
Delay
Specifies a percentage of the delayed signal to be added back into the delay to create multiple decaying
Feedback
echoes.
Controls the amount of echo.
Mix
DeNoiser effect
The DeNoiser effect automatically detects tape noise and removes it. Use this effect to remove noise from analog
recordings, such as magnetic 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.
Noisefloor
Stops the noise floor estimation at the current value. Use this control to locate noise that drops in and out of a clip.
Freeze
Specifies the amount of noise to remove within a range of –20 to 0 dB.
Reduction
Sets an offset value between the automatically detected noise floor and the value defined by the user. This is
Offset
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
AutoGate
background signals in recordings, such as a background signal in a voice-over. Set the gate to close whenever the
