Pitch Shift Plug-Ins : X-Form : X-Form Displays and Controls Overview : X-Form Time Section Controls

X-Form Time Section Controls
The Time section of X-Form provides controls for specifying the amount of time compression or expansion as well as the timebase used for calculating TCE. Adjust the Time control to change the target duration for the processed audio.
 
Original
Displays the Start and End times, and Length of the edit selection. Times are displayed in units of the timebase selected in the Units pop-up menu.
Processed
Displays the target End time and Length of the processed signal. Times are displayed in units of the timebase selected in the Units pop-up menu. You can click the Processed End and Length fields to type the desired values. These values update automatically when adjusting the Time control.
Tempo
Displays the Original Tempo and Processed Tempo in beats per minute (bpm). You can click the Original Tempo and Processed Tempo fields to type the desired values. The Processed Tempo value updates automatically when adjusting the Time control.
Unit
Select the desired timebase for the Original and Processed time fields: Bars|Beats, Min:Sec, Timecode, Feet+Frames, or Samples.
*
X-Form does not receive Bars|Beat and Feet+Frame information from Pro Tools 7.0 or 7.1. Consequently, Bars|Beats and Feet+Frames are displayed as “N/A.”
Shift
Displays the target time compression or expansion as a percentage of the original. Adjust the Time control or click the Shift field and type the desired value. Time can be shifted by as much as 12.50% to 800.00% of the original speed (or 8 times to 1/8 of the original duration) depending on which Range button is enabled (2x, 4x, or 8x). The default setting is 100%, or no time shift.
The Shift field only displays up to 2 decimal places, but lets you type in as many decimal places as you want (up to the IEEE standard). While the display rounds to 2 decimal places, the actual time shift is applied based on the number you typed. This is especially useful for post-production pull up and pull down factors (see Using X-Form for Post Production Pull Up and Pull Down Tasks).
2x, 4x, and 8x Range Buttons
The 2x, 4x, and 8x Range buttons set the possible range for the Time Shift, Pitch Shift, and Formant Shift controls.
2x
Lets you apply Time Shift, Pitch Shift, and Formant Shift from 50.00% to 200.00% (where 50.00% is 2 times the original duration and 200.00% is 1/2 of the original duration).
4x
Lets you apply Time Shift, Pitch Shift, and Formant Shift from 25.00% to 400.00% (where 25.00% is 4 times the original duration and 400.00% is 1/4 of the original duration).
8x
Lets you apply Time Shift, Pitch Shift, and Formant Shift from 12.50% to 800.00% (where 12.50% is 8 times the original duration and 800.00% is 1/8 of the original duration).
*
When changing to a smaller Range setting (such as switching from 8x to 2x), the Time Shift and Pitch Shift settings are constrained to the limits of the new, smaller range. For example, with 8x enabled and Time Shift set to 500%, switching to 2x changes the Time Shift value to 200%.
