Revoice Pro 4.3 adds SmartAlign as an option in the Timing section of the APT Process settings.
When this option is checked, the system looks for and aligns only matching sections in Guide and Dub audio, not processing long gaps of silence in either. This can help to avoid the need to break up longer sections into segments for processing.
APT SmartAlign Presets
The APT Presets menu includes two separate sets of Factory Presets, separated by a horizontal line. Those below the line are versions of the basic Presets, but with SmartAlign enabled.
