What is VocAlign Project 5?

Introduction to VocAlign Project 5 

VocAlign Project 5 is a powerful but easy-to-use plugin that can automatically match the timing of one audio signal to the timing of another audio signal. 

What's New?

The two main improvements over previous versions of VocAlign Project 3 are:

  1. The User Interface - this is a complete transformation in the VocAlign range to match VocAlign Ultra
  2.  SmartAlign - This update to the alignment algorithm makes VocAlign Project 5 faster and easier than ever. This new Synchro Arts' technology was first released in Revoice Pro 4.3.

We’ve also added:

  • An alignment tightness control.
  • A library of presets to help you quickly get the right settings for a variety of jobs and signal types.
  • Two view windows showing waveforms or signal energy displays.
  • A movable Timing Offset Display showing  points of alignment in the Guide and Dub waveforms
  • Scaleable interfaces

What does VocAlign Project 5 do?

In a nutshell, VocAlign Project 5 enables dialogue editors and music producers to quickly and easily align the timing of one vocal or instrumental performance with another and easily adjust the tightness to the amount you need.

As any dubbing editor or music producer knows, lip-syncing and double tracking vocals and instruments can be a painstaking, laborious process, highly dependent on the ability of the performer to repeat themselves accurately, and often involving many takes to get a workable final result.

With VocAlign Project 5 brought into the process, you can let the artist concentrate on creating a great performance, without worrying about the detailed timing mismatches relative to the guide track. The plugin automatically and transparently applies the required amount of variable time-stretching to match the Dub to the Guide, saving studio and artist time, and delivering natural-sounding results.

Perhaps most importantly, VocAlign Project 5 allows your artist to produce their best performance, free from the stressful rigidity and repetition traditionally associated with re-recording or doubling tracks.

Main Applications

VocAlign Project 5 can be used for all manner of corrective and creative purposes, including:

In post production:

  • Syncing replacement dialogue for film and video.
  • Tightening up lip-syncing with foreign language dubs.

In music production:

  • Double-tracking vocal and instrumental parts.
  • Replacing the vocals in a music video shoot with a production track, to achieve perfect lip-sync.

How does it work? 

VocAlign Project 5 works by applying varying amounts of time-stretching and compression to one signal – the ‘Dub’ – to align its energy peaks and troughs over time with those of a ‘Guide’ signal.

VocAlign Project 5 does its processing in three main steps:

  1. VocAlign Project 5 analyzes the Guide and Dub audio signals using identical spectrum analyzers to produce time-varying energy patterns for both signals.
  2. Advanced pattern recognition techniques are used to compare the two energy patterns and determine the best way to ‘warp’ the Dub’s timing to align it to the Guide signal. A time-warping path is created to specify the best time-distortion of the Dub for matching to the Guide according to the “Matching” tightness setting.
  3. The time-warping path feeds into an audio editing processor that time-stretches and -compresses the Dub audio signal to create the Aligned version. 

It is this time-aligned version of the Dub that is the processed Output, which is returned to the host DAW.
