Having this ..., VOCAL ALIGN

..., was the most useful tool I had for retaining professionally done natural sounding vocal doubles (and more)

It works on guitars as well : http://www.synchroarts.com/products/vocalign-pro/overview

I now actually have Revoice Pro which actually includes vocal align plus much more , but vocal align on it's own is excellent. It is also not expensive to buy, and get a superb job done - much faster, and better than any other similar type plugs I tried .

VOCALIGN PRO 4


VocALign Pro 4 is the most advanced version of the legendary VocALign program, providing instant tight alignment of one audio signal to another. Simply capture a Guide signal with the right timing, capture a Dub signal to be aligned, press one button, and a new aligned Dub is generated and returned to your DAW.



Main Features


Automatically analyzes the energy patterns of two audio signals and edits one to match the timing of the other.
Includes basic and advanced alignment and editing algorithms.
Works with voice, musical instruments and sound effects.
Provides time saving and quality benefits for ADR, tightening double tracked vocals and backing harmonies, foreign language dubbing, etc.
Simple, intuitive Audio Suite, AAX, VST3 and AU plug-in integration for most popular DAWs. (See Features)
The Pitch of aligned audio is unchanged.



FEATURES


VocALign PRO 4 automatically aligns two audio signals so that the timing of one matches the other
Simple, intuitive operation with Audio Suite, AAX, VST3 and AU plug-ins work with popular DAWs
Sophisticated pattern matching techniques
Rejects guide track noise
Works with different speakers, singers, words, instruments and sounds
The aligned audio can be auditioned within VocALign PRO 4
Scrolling, scalable display allows instant visual confirmation of sync
User interface allows adjustment of selected audio regions for processing
User-adjustable processing presets ensure optimal performance
Pitch of aligned audio is unchanged

Advanced Features and Functions in VocALign Pro 4

Increased alignment accuracy:- achieved with a more sophisticated pattern recognition algorithm.
Enhanced TimeMod (time compression/expansion):- optimised for single-pitch signals. Basic TimeMod algorithm also available for more complex signals.
Protected signal blocks:- user can mark sections of the Replacement (Dub) signal to not be time-modified during alignment.
Comprehensive audio preview options:- allows playback of sections or the whole signal(s) before and after alignment, individually or together. (In Pro Tools version)
User settable Synch Points:- targets audio alignment at specified pairs of points in the two signals.
Longer maximum signal length:- Up to 5 minutes
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.




WHY USE VOCALIGN PRO 4?


Audio Post production and multimedia

Perfect lip-syncing
Reduced studio time re-recording dialog
More accurate and convincing foreign dialogue replacement
Tighter foley and sound effects tracks
Music editing

Perfectly-aligned double-tracked vocals and/or instruments
Tighter and clearer backing vocals
Shorter overdub sessions
Easy re-grooving of recorded vocals for remixing




HOW DOES VOCALIGN PRO WORK?

VocALign works by applying varying amounts of time stretching or compression to one signal (called the ‘Dub’) to make its energy peaks and troughs align in time with a ‘Guide’ signal. It does this in three main steps as shown in the block diagram below.



VocALign analyses the captured Guide and Dub audio signals using identical spectrum analysers to produce time-varying energy patterns.
Then it uses advanced pattern recognition techniques to examine the energy patterns and determine the best way to ‘warp’ the time structure of the Dub signal so that its energy pattern is matched to that of the Guide. The time-warping path describes the best time-distortion of the Dub for matching to the Guide.
The time-warping path is fed to an audio editing processor that time-compresses and expands the Dub audio to create the aligned version based on the path. It is this edited version of the Dub that is returned to the audio editing software for the desired use.
Note: In the above diagram, the spectrum analyser colours match those used in the VocALign screen for Guide and Dub audio signals and controls.
