Start Next Auto-Ducking - Configuration

For Start Next Auto-Ducking there are two groups of parameters.

Parameters to detect the audio segments in the recording. The Attack* parameters detect the beginning of the audio segment and the Hold* parameters detect the end of the audio segment.

Default Values

Description

Amplification

200.0...0.0

-10

Amplification in dB for ducking settings.
When an audio is ducked it will be lowered by %Amplification% dB in the ducking area.
"Amplification" is used for duck targets ducked by duck source audios and by audio segments from the recording.

AttackOffset

0...100000

150

AttackOffset in milliseconds for Start Next Auto-Ducking.
The "AttackOffset" will be used together with the "AttackTime", the "AttackThreshold" and the "ThresholdTolerance" to detect the start of an audio segment in the recording.
The %AttackOffset% ms offset will compensate for internal delays by the detection logic with a default value of 150 ms.
The %AttackOffset% ms offset is not needed to compensate for the %AttackTime% ms offset.
The %AttackOffset% ms offset can also be used to further correct the detected start position of an audio segment in the recording to the left or the right in the timeline.

AttackThreshold

100.0...0.0

-30.0

AttackThreshold in dB for Start Next Auto-Ducking.
The "AttackThreshold" will be used together with the "AttackTime", the "ThresholdTolerance" and the "AttackOffset" to detect the start position of an audio segment in the recording.
The start of an audio segment in the recording is detected if the signal is above %AttackThreshold% dB for at least %AttackTime% ms and in at least %ThresholdTolerance% percent of the values

AttackTime

0...100000

100

AttackTime in milliseconds for StartNext-Autoducking.
The "AttackTime " will be used together with the "AttackThreshold", the "ThresholdTolerance" and the "AttackOffset" to detect the start position of an audio segment in the recording.
The start of an audio segment in the recording is detected if the signal is above %AttackThreshold% dB for at least %AttackTime% ms and in at least %ThresholdTolerance% percent of the values.

FadeDown

0...100000

1000

Must be zero or a positive number not greater than 100000.
FadeDown in milliseconds for ducking settings in Start Next Auto-Ducking.
"FadeDown" is used together with "FadeDownCurveType" to define the form of the fade down part of the ducking curve.
The distance between the start and the end of the fade down is %FadeDown% ms.
"FadeDown" is used for duck targets ducked by duck source audios and by audio segments from the recording.

FadeDownAfter

0...100000

500

FadeDownBefore in milliseconds of the ducking settings in Start Next Auto-Ducking.
"FadeDownBefore" defines the alignment between the fade down curve and the duck position.
"FadeDownBefore" is used for duck targets ducked by duck source audios and by audio segments from the recording.
If %FadeDownBefore% is 0 ms, the fade down starts at the duck position.
If %FadeDownBefore" is 500 ms, the fade down starts 500 ms before the duck position.

FadeDownCurveType

Linear, Log1, Log2, LogMinus2

The shape of the fade curve. Must be one of Linear, Log1, Log2, LogMinus2. These are the same curve shapes as those which you can select in OTM when interactively creating fade-ins, fade-outs, and cross fades.

FadeDownCurveType of the ducking settings

"FadeDownCurveType" is used together with "FadeDown" to define the form and size of the fade down part of the ducking curve.
"FadeDownCurveType" defines the form of the fade down curve.

The supported values:

- Linear - Creates a linear curve.
- Log1 - Creates a Log 1 curve.
- Log2 - Creates a Log 2 curve.
- LogMinus2 - Creates a Log -1 curve.

FadeUp

0...100000

1000

FadeUp in milliseconds for ducking settings.
"FadeUp " is used together with "FadeUpCurveType" to define the form of the fade up part of the ducking curve.
The distance between the start and the end of the fade up is %FadeUp% ms.
"FadeUp" is used for duck targets ducked by duck source audios and by audio segments from the recording.

FadeUpBefore

0...100000

500

FadeUpBefore in milliseconds for ducking settings.
"FadeUpBefore" defines the alignment between the fade up curve and the unduck position.
"FadeUpBefore" is used for duck targets ducked by duck source audios and by audio segments from the recording.
If %FadeUpBefore % is 0 ms, the fade up starts at the unduck position.
If %FadeUpBefore " is 500 ms, the fade up starts 500 ms before the unduck position.

FadeUpCurveType

Linear, Log1, Log2, LogMinus2

FadeUpCurveType for ducking settings.
"FadeUpCurveType" is used together with "FadeUp" to define the form and size of the fade up part of the ducking curve.
"FadeUpCurveType" defines the form of the fade up curve.

The supported values are:

- Linear - Creates a linear curve.
- Log1 - Creates a Log 1 curve.
- Log2 - Creates a Log 2 curve.
- LogMinus2 - Creates a Log -1 curve.

HoldOffset

0...100000

150

HoldOffset in milliseconds for Start Next Auto-Ducking.

The "HoldOffset" will be used together with the "HoldTime" the "HoldThreshold" and the "ThresholdTolerance" to detect the end of an audio segment in the recording.
The %HoldOffset% ms offset will compensate for internal delays by the detection logic with a default value of 150 ms.
The %HoldOffset% ms offset is not needed to compensate for the %HoldTime% ms offset.
The %HoldOffset% ms offset can also be used to further correct the detected end position of an audio segment in the recording to the left or the right in the timeline.

HoldThreshold

-100.0...0.0

-30

HoldThreshold in dB for StartNext-Autoducking.

The "HoldThreshold" will be used together with the "HoldTime", the "ThresholdTolerance" and the "HoldOffset" to detect the end position of an audio segment in the recording.
The end of an audio segment in the recording is detected if the signal is below %HoldThreshold% dB for at least %HoldTime% ms and in at least %ThresholdTolerance% percent of the values.

HoldTime

0...100000

1000

HoldTime in milliseconds for Start Next Auto-Ducking.
The "HoldTime " will be used together with the "HoldThreshold", the "ThresholdTolerance" and the "HoldOffset" to detect the end position of an audio segment in the recording.
The end of an audio segment in the recording is detected if the signal is below %HoldThreshold% dB for at least %HoldTime% ms and in at least %ThresholdTolerance% percent of the values.

ThresholdTolerance

0..100

ThresholdTolerance in percent for Start Next Auto-Ducking.

The "ThresholdTolerance" will be used together with the "AttackTime", the "AttackThreshold" and the "AttackOffset" to detect the start position of an audio segment in the recording. The start of an audio segment in the recording is detected if the signal is above %AttackThreshold% dB for at least %AttackTime% ms and in at least %ThresholdTolerance% percent of the values.

The "ThresholdTolerance" will be used together with the "HoldTime", the "HoldThreshold" and the "HoldOffset" to detect the end position of an audio segment in the recording. The end of an audio segment in the recording is detected if the signal is below %HoldThreshold% dB for at least %HoldTime% ms and in at least %ThresholdTolerance% percent of the values.
