To adjust the APT settings after creating an APT Process, you you need to make sure you have selected the correct APT Process before you open its APT Control Panel.

That means you must have selected either the APT Output audio, the Dub Process Control Block, or the correct Guide Process Control Block (where there are more than one APT Process Control Blocks in a stack). Refer to Process Control Panel for more information


Press P key to open the Control Panel as shown right.

You can repeatedly try other Presets or modify the parameters in the Control Panel and listening to the result.

The APT Control Panel can remain open and, while signals are playing, you can adjust controls and the process will be applied.

See Rendering and background processing to determine whether audio is rendered automatically after changes are made, or needs some action from you before it can be played.



APT Panel Controls


Presets (shown top right with "Factory Defaults") allows you to select Factory or  your own previously saved "User" settings, and to save your own User Preset settings.


There is also a Compare function to compare saved versions of a Process, and a Pinning control to keep this Process Control Panel open (while opening other Control Panels).


For APT Processes there is a Process Lock button (shown locked red in the picture below) below the Compare and Presets section. This fulfils the same function as the lock button on the Process Control Track, and will stop further automatic processing from taking place. This is to stop any optional manual edits from being overwritten.





Explanation of Settings and Pop-up menus in APT Control Panel

Each of the controls shown has a "pop-up" explanation which will appear shortly after hovering the mouse pointer over a slider control or parameter display box. Further details of controls and what you might be able to do with them are given in the table below.


Control

Description

AUTOMATIC TRANSFER

  • If Lock icon OFF, all processing below is available.
  • If Lock icon ON (Red), turns all further automated processing off.

Dialog/Music

  • Dialog = If Pitch switch is on, Guide pitch is used exactly as the basis for the new Dub pitch - but the amount of modifications will be controlled by the settings displayed in the Pitch settings section - detailed below.
    (This mode also recreates the processing used in Revoice Pro 3.)

  • Music = If Pitch switch is on, the Guide and Dub pitch traces are separated into long term average variations (e.g. over a note's duration) and short term variations (e.g. musical features such as vibrato).  The amount of modifications will be controlled by the settings displayed in the Pitch settings section- detailed below.

Timing

  • ON = Transfer Guide's timing to Dub automatically but obeying the Tolerance and Alignment settings.
  • OFF = The Guide features of Pitch or Level, if ON, will be transferred to the Dub at the correct timing but without modifying the Dub's timing.

Other Timing Controls 


  • Alignment - Choose desired time-alignment flexibility


Alignment Setting

Main characteristics

Lowest Flexibility

Alignment is least flexible, creates fewest edits. Sound quality may be best.

Low Flexibility

Alignment is not very flexible, creates fewer edits. Sound quality may be better.

Normal Flexibility

(Default)

Try this first as it works

best in most cases, balancing good alignment with moderate editing.

High Flexibility

Alignment is the most flexible and allows more editing, which may

compromise sound quality

Maximum Compression

Tries to match the Guide by time compressing the aligned audio as much as possible.

Maximum Expansion

Tries to match the Guide by time-expanding the aligned audio as much as possible

Normal Flexibility + Pitch

If energy pattern does not change but pitch in Guide and Dub change together, this can work in signals with legato pitch changes.



  • Tolerance - (Tight/Loose) sets maximum allowed offset in timing difference.
  • Protect Transients - Reduces possible distortion effects. (Default: ON)
  • Max Shift - Reducing values restricts the maximum time shift from its original position allowed for the Dub audio.
    (Default: no Limit)
  • Soft Limiting for Shift- Introduces a more flexible boundary for the Max Shift setting. (Default: ON)

Pitch

  • OFF = Guide Pitch will NOT be transferred to the Dub
  • ON = Transfer Guide signal's pitch to the Dub (time aligned).

Other Pitch Controls  

Dialog Mode


Guide pitch used directly as first basis for pitch modifications of the Dub.


In this mode, the process

  • Tolerance - (Tight/Loose) sets maximum % allowed pitch difference.

  • Transfer Strength – Proportion of correction factor transferred. 100% means use only the Guide's pitch, 0% means use only the Dub's pitch.


  • Pitch correction rule (Drop Down menu):
    • Nearest Octave – transfer exact pitch but allow natural octave jumps
    • Absolute – transfer exact pitch
    • Relative – pitch change relative to Guide pitch at “phrase” starts
    • Monotone – all pitch changed to measured average pitch


Music Mode

In this mode, the process first separates the Guide and Dub pitch traces into average (Tuning) and modulations (Fit)

  • Tuning - Match long term average variation of Dub to Guide's.
    • 0% = Keep Dub tuning
    • 100% - Apply Guide longer term average tuning to Dub.
  • Fit - short term variations of Dub to Guide's (e.g. vibrato) from 0% (not at all) to 100% exact match.


Music and Dialog Modes


  • Offset – modify output signal pitch by % shown
  • Smooth Jumps in Pitch – (Default ON)
  • Advanced Algorithm – Try ON if hear artefacts. (Default OFF)
  • Hi Res Mode – For higher pitched signals - Try ON if hear artefacts. (Default OFF)
  • Guide (or Dub) Lowest Frequency - set the lowest pitch to be measured in the Guide (or Dub)
  • Guide (or Dub) Highest Frequency – set the highest pitch to be measured in the Guide (or Dub)


Level

  • ON = Transfer Guide signal level to Dub (time-aligned).
  • OFF = Do not transfer signal level

Other Level Controls

  • Tolerance - (Tight/Loose) sets maximum % allowed level difference.
  • Transfer Strength – Proportion of correction factor transferred
  • Offset – add a constant gain to the Dub level trace.
  • Keep Dub's Average Level - modifications are made relative to Dub average
  • Attack – Slew time (smoothing) applied to increases in level changes (Default = 0.01sec)
  • Decay –Slew time (smoothing) applied to decreases in level changes (Default = 0.03sec)

Display


 

  • Energy Band: Display the selected octave-wide frequency band used for energy measurements that are input to the alignment algorithm.
