OVERVIEW
VocALign is an audio alignment tool from
SynchroArts (http://www.synchroarts.co.uk)
which will automatically synchronize two audio
signals at the touch of a button. You can control
most VocAlign functions from Digital Performer
while VocAlign runs in the background.
VocAlign works by automatically “micro-editing”
the new or replacement audio signal to align the
timing of its modulations to match a guide signal.
This can be useful for lip-syncing, foreign dialogue
replacement, tightening-up of double-tracking,
backing vocals and instruments and modifying the
timing of one music track to match another.
HOW IT WORKS
1 Be sure VocAlign is running in the background.
2 In Digital Performer, select a soundbite that will
serve as the guide file for the audio you wish to
align.
3 Under the Audio menu, select Set Guide File
from the VocAlign sub-menu:
4 Select the soundbite you wish to align to the
guide file.
5 Under the audio menu, select Voc A l ig n > Set
Dub File. VocAlign first analyzes the two signals’
time-varying energy through filter banks.
6 Under the audio menu, select VocAlign > Align
and spot audio.
