Bass
The Bass effect allows you to increase or decrease lower frequencies (200 Hz and below).
Boost specifies the number of decibels by which to increase the lower frequencies.
Channel Volume
The Channel Volume effect allows you to independently control the volume of each
channel in a stereo or 5.1 clip or track. Each channel’s level is measured in decibels.
DeNoiser
The DeNoiser effect automatically detects tape noise and removes it. Use this effect to
remove noise from analog recordings, such as magnetic tape recordings.
Noise floor
Specifies the level (in decibels) of the noise floor as the clips plays.
Freeze
Stops the noise floor estimation at the current value. Use this control to locate
noise that drops in and out of a clip.
Reduction
Specifies the amount of noise to remove within a range of –20 to 0 dB.
Offset
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.
Delay
The Delay effect adds an echo of the audio clip’s sound that plays after a specified amount
of time.
Delay
Specifies the amount of time before the echo plays. The maximum is 2 seconds.
Feedback
Specifies a percentage of the delayed signal to be added back into the delay to
create multiple decaying echoes.
Mix
Controls the amount of echo.
Dynamics
The Dynamics effect provides a set of controls that can be combined or used indepen-
dently to adjust audio. Use either the graphical controls in the Custom Setup view, or
adjust values in the Individual Parameters view.
Gate
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
voiceover. 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.
