Revoice Pro 4

The APT Process transfers user-selected timing, pitch and level characteristics of a good "Guide" audio signal to one or more audio signals - automatically.

 

Applications for the APT process include:

Vocal and instrumental double tracks: Tighten the timing, pitch and vibrato of “stacked” tracks while keeping them natural-sounding.

Dialog replacement: Lip-sync dialogue (ADR) and vocals by the same or different performers, even when there are noisy guide tracks.

Transfer a performance: Change the inflection in dialog (ADR, voice-overs etc.) with the desired pattern changes provided by recording the director or dialog editor's voices.

Fix corrupted live vocal recordings: Replace and sync problematic vocals with clean retakes.

Description of the APT Processing

The user loads or transfers the Guide and Target (Dub) audio to be processed into the Revoice Pro program from DAWs or audio files. The Guide signal should have the "perfect" features: either timing, pitch or both.

However, if your Guide audio needs further time or pitch modifications, you can use Revoice Pro's new built-in Warp function to quickly and transparently adjust the Guide's (or lead harmony parts') timing and pitch.

In Revoice Pro, you can insert APT function blocks wherever you want them in dedicated "tracks" under each audio track that show where the processing starts and stops. You also chose the initial settings.

The APT process first determines the timing relationship between key features of the Guide and Target (Dub) audio signals using state-of-the-art pattern recognition algorithms based partly on Synchro Arts' VocALign technology.

Next, the APT process measures performance-related features (such as timing, pitch, vibrato and level) of both the "Guide" (which usually has certain preferred performance characteristics) and one or more Targets (Dub) signals.

User-selected Guide performance features are transferred to the Target audio to create a new Modified Target signal with the selected Guide features.

The transfer process usually includes the timing alignment, so Guide features are incorporated at precisely the correct places along the Target. However, this is an option.

If satisfactory, the processed Dub(s) can be instantly transferred back to the DAW via a number of methods including Revoice Pro Link plug-ins, drag & drop or copy & paste.

Important features:

 

Warp Processes: Manually adjust Timing, Pitch and Level

Simple, fast adjustments with maximum quality- for voice and monophonic instruments

In Revoice Pro 4, manual Pitch and Time Warping of audio is intuitive, making it easy to select and manipulate timing and pitch whilst providing the highest audio quality. The controls allow selection over any range and cursor tool changes to show what will move. Automatic snap to pitch option, plus play loops and undo functions make adjustments fast and easy.

Applications for Warp processes

• Improving or altering the pitch and/or timing of tracks that are used as Guide tracks in APT or Doubler processes.
• Correcting or altering the pitch of a harmony track before using it as a Dub input to an APT process that will have only its timing aligned to the Guide. The output of this APT process can then become a harmony Guide track for automatically aligning the time and pitch of double tracks of this harmony part.
• Manually adjusting the pitch and time of a solo vocal or any voice recording.
• If required, making minor adjustments to the features in the output of an APT process.
• Modifying signal levels.

A powerful advantage of keeping time and pitch adjustments within Revoice Pro 4 is that any additional time and/or pitch changes to Guide or Input tracks will be passed automatically into the outputs of all processes using these inputs.

This means that dependant audio tracks will always be in time and in sync instantly.

Warp Processing Details

There are now three new methods for manual Timing and Pitch Warping audio in Revoice Pro. However, the tools availble in all of these are operated similarly.

The quick-access cursor tool's function changes simply by moving the cursor position around the note selection blocks. This way, pitch traces can be shifted, squeezed, tilted and even inverted instantly by dragging the note-box sides or corners.

Time and level can be manipulated similarly and easily.

Moreover - there is a Correct Pitch function for a quick snap-to grid process which will automatically adjust a large proportion of out-of-tune notes to more acceptable tunings.

However, in any processing, the most important element is sound quality - which in Revoice Pro 4, remains natural and transparent for moderate changes.

For working with low or high pitched instruments or voices, the pitch processing ranges can be extended down to bass instrument ranges or up to flute ranges- to maintain the highest quality processing.

The WARP REGION Process

• Adjustments are made to a single audio region in same track as the input audio Region and the adjusted output is heard replacing the input audio.
• This is meant for making large and small corrections or creative changes to the timing and pitch of voice and monophonic instruments to create perfected lead, harmony, ADR or voice over parts.

The WARP Process

• Like the APT or Doubler, the Warp process can (from part of a region or even from multiple regions) and allow creative adjustments and corrections to be applied to the input audio. But in this case, the Warp Process results are sent to an Output track - i.e. not in the same track as the input audio.
• The Warp process takes its input from any length of audio in one track, from part of one region to spanning multiple regions. The output of the Warp process is sent to a designated output track where the adjustments are made. The input track is left unchanged.

Warp Points

• Warp points can be used to time stretch the signal between two points.
• Vibrato Warp Points allow you to time stretch or compress signals containing vibrato without modifying the vibrato rate.
• You can also use speed points to gradualy change the rate of time stetch.
