Advanced Voice Tracking (AVT) Configuration

Parameter Configuration

Many aspects of AdvancedVoiceTracking (AVT) can be tailored to suit the needs of your radio station, or simply to meet personal preferences. To create configuration values, you need the "Admin" tool which comes as a part of the Digas System.

Attention!
Please be sure to know how to configure OTM for DigAIRange and/or Turbo Player before you modify configured settings.

AVT parameters are stored in the "AdvancedVoiceTracking" subkey of the "Extra" subkey. The "Extra" subkey is a subkey of the OTM configuration folder.

The "AdvancedVoiceTracking" subkey contains three subkeys which are used for different aspects of AVT configuration:

DuckingParameters that control the duck/unduck behavior
FadeOutParameters that control the fade-out function
LevelingParameters that control the volume adjustment keys

The association between key codes and AVT functions (as mentioned in the "Overview" section) is maintained by the calling program, i.e., DigAIRange or Turbo Player. You should use the respective user interface to define these data.

"Ducking" Parameters

They control the shape, width, depth, and position of fade-downs and fade-ups that are initiated by the "START DUCKED/DUCK/UNDUCK" key.

The bold and underlined value is the default value.

ModuleParameterValueDescription

Amplification

200.0...0.0

 -15.0

  • Amplification in dB for ducking settings in Start Next Auto-Ducking.
  • 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.

FadeDown

0...100000

1000

  • Must be zero or a positive number not greater than 100000.
  • FadeDown in milliseconds for ducking settings.
  • "FadeDown" is used together with "FadeDownCurveType" to define the form of the fade down part of the ducking curve.

  • "FadeDown" is used for duck targets ducked by duck source audios and by audio segments from the recording.

FadeDownBefore

0...100000

500


With this parameter you can let the fade curve start before the key is pressed. Any positive value shifts the fade curve into the past. The value 0 lets the fade-down start synchronously with the key-press.

  • "FadeDownBefore" defines the alignment between the fade down curve and the duck position.
  • FadeDownBefore the offset in milliseconds 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 fadeup 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.

"FadeOut" Parameters

These parameters are stored in the "FadeOut" subkey. They control the fade-out function which is triggered by pressing the "START NORMAL/FADE OUT" key during playout of the respective element.

Reference Path

(lightbulb) "..|DigAIRange|Crossfade\Extra|AdvancedVoiceTracking|FadeOut" or "..|TurboPlayer|GUI|Windows|CFM|1|Extra|AdvancedVoiceTracking|FadeOut"

ModuleParameterValueDescription

FadeCurveTypeLinear, Log1, Log2, LogMinus2

FadeCurveType for fadeout settings in AdvancedVoiceTracking Mode.

  • "FadeCurveType" is used together with "FadeTime" to define the form and size of the fade out curve.
  • "FadeCurveType" defines the form of the fade out 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.

FadeTime

0...100000

2500

FadeTime in milliseconds for fade out settings in AdvancedVoiceTracking Mode.

  • "FadeTime" is used together with "FadeCurveType" to define the form and size of the fade out curve.
  • The distance between the start and the end of the fade out is %FadeTime% ms.
  • Must be zero or a positive number not greater than 100000.

"Leveling" Parameters

These parameters are stored in the "Leveling" subkey. They refer to the operation of the ↑ and ↓ volume adjustment keys.

Reference Path

(lightbulb) "..|DigAIRange|Crossfade\Extra|AdvancedVoiceTracking|Leveling" or "..|TurboPlayer|GUI|Windows|CFM|1|Extra|AdvancedVoiceTracking|Leveling"

ModuleParameterValueDescription

DistanceOfFadePoints

0...5000

100

Defines the minimal distance in milliseconds, between any two adjacent fade points when volume is adjusted. This value is used to honor limitations of the play-out software or hardware which may not be able to process fade points that are too close to each other. Must be zero or a positive number not above 5000.

This restriction is applied for non-linear fade curves, as well when one of the ↑ or ↓ buttons is pressed (which in fact also creates a small fade).

  • DistanceOfFadePoints in milliseconds for leveling settings in Advanced Voice Tracking Mode.
  • "DistanceOfFadePoints" is used together with "LevelModification" to define the size of the fade for level up/down.
  • The distance between the start and the end of the fade is %DistanceOfFadePoints% ms.

LevelModification

0.5...5.0

1.0

Amount in dB by which the fade curve is increased or decreased when one of the ↑ or ↓ buttons is pressed. Decimal digits are allowed; a dot (fullstop, period) servers as decimal separator. Must be positive in the range of 0.5 to 5.0.

  • LevelModification in dB for leveling settings in AdvancedVoiceTracking Mode.
  • "LevelModification" is used together with "DistanceOfFadePoints" to define the size of the fade for level up/down.
  • The height in dB between the start and the end of the fade is %LevelModification% dB.

MinimumDuckLevel

-10.0...-3.0

-6.0

Defines the threshold in dB by which OTM distinguishes between "low volume" and "high volume", in the context of the DUCK/UNDUCK key.
The DUCK/UNDUCK key increases the volume to full (unducks) if the current fade curve is below this limit; it decreases the volume to the Amplification value, if the current fade curve is not below the limit.
Although any negative value between -10.0 and -3.0 is allowed, you should define this parameter to be approximately one half of the Amplification value.

  • MinimumDuckLevel in dB for Leveling settings in AdvancedVoiceTracking Mode.
  • The "MinimumDuckLevel" controls the ducked state of the AdvancedVoiceTracking mode.
  • If the current duck level is below or at the same level of %MinimumDuckLevel% dB, the state is ducked.
  • In the ducked state the fade line and the duck symbol in the track header are shown in blue.
  • The ducked state can be reached with the level down shortcut(s) or with the duck shortcut(s).

Keypad or Keyboard Configuration

The functions of AdvancedVoiceTracking are only available via keyboard shortcuts; they do not have buttons or menu entries in the user interface. The only exception is the "STOP" function which is also available through the STOP button 

. Keyboard shortcuts are defined in the calling application that is in DigAIRange or Turbo Player. Please refer to Keyboard Shortcuts for more details.

As was already mentioned, AdvancedVoiceTracking handling becomes much easier when you use an external keypad that is specifically configured for use with this functionality. In this case the configuration of the keypad must match that of the keyboard shortcuts. For example, if you have assigned the key combination Alt+R to the function "Enter Advanced Voice Tracking", then you must configure the keypad so that the "ENTER AVT" key emits the key code Alt+R.

The following table lists shortcut names as you can see them in the configuration dialog of DigAIRange and the key names as they were used in this document.
