Benefits using VocALign PRO

Editors in film, video post production, music and multimedia now have more control over any required audio alignment editing. They will be able to target the alignment of the replacement signal (Dub) to the Guide where it is required and can keep sections of the Dub from being edited by specifying Protected areas. The Sync Points feature can help the algorithm sync matching points in very different signals.

These features will be invaluable for certain types of noisy or reverberant Guide signals and especially useful for foreign dialogue replacement. In addition, the new Preview Controls allow much more detailed examination of parts or all of the two signals, together or separately, both before or after alignment to confirm the quality of editing and alignment.

The other features such as improved overall quality of automatic alignment and micro-editing will save the user even more time and frustration.
