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.
- AttackTime
- AttackThreshold
- AttackOffset
- HoldTime
- HoldThreshold
- HoldOffset
- ThresholdTolerance
Parameters that decides which form the ducking curve have and how it is applied.
- Amplification
- FadeDown
- FadeDownBefore
- FadeDownCurveType
- FadeUp
- FadeUpAfter
- FadeUpCurveType
Parameter Descriptions:
The bold and underlined value is the default value.

Module | Parameter | 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 | 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. - 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.

- 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.
