v5 Synchro Arts ReVoice Pro

APT – Audio Performance Transfer Process

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 the 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:

• The “tightness” of the transferred feature can be controlled to allow natural acceptable differences to pass through unchanged.
• Optional user-inserted “Protected Regions” allow selected sections of the Dub signals to be left unchanged in timing or pitch by the APT process.
• The automatic APT processing can be followed by (or replaced by) manual editing of the output features.
• APT Pitch (and other feature’s) processing settings can be made time-varying (automated).
• “Process-based” solo switching, via single keys, provides instant audition to compare inputs and outputs one or two signals at a time.
• The effects of any changes made to APT control panel parameters will be immediately visible (after rendering) in the displayed output graphics of pitch, level and waveform traces.
• Multiple Dub signals can use the same Guide and be efficiently processed at the same time.
• A comprehensive Preset system allows saving and reusing settings

Case Study – Replacing Noisy Dialogue

When José Luis Díaz found himself with location dialogue ruined by the sound of vehicle noise he turned to Revoice Pro to rescue the project.

“I had a take with some words ruined by the sound of moving vehicle noise. At first, I tried to clean it with the top audio “cleaning” product but it was not possible. Then I searched in alternative takes and discovered one where those words were clean, but the reading was different and the pitch of the voice was too low. So it was not possible to simply replace the noisy words with the clean words. Nobody speaks in that gymnastic way.

I then tried Revoice Pro, and used the original noisy dialogue as the guide and words from the alternative take as the “dub”. After a few attempts, I had clean location dialogue that had both matching time and pitch. This was not previously possible without Revoice Pro.”

Doubler

The Doubler – instantly create natural-sounding mono and stereo double tracks for voice and instruments or, crank the parameters for more extreme modulation style effects on your tracks. A great time-saving process often referred to as ‘the secret weapon’ in modern vocal production.

Applications for Doubler

• Creating realistic double tracks from vocal or instrument recording when no double track is available.
• Create a wide range of special modulation effects

Process Details

• Inputs can be mono or stereo signals.
• Doubler automatically creates natural-sounding mono or stereo double tracks in seconds.
• Provides controls for modifying timing variations, formats, and vibrato.
• Supports extreme parameter variations to create special effects.
• Comprehensive user Preset system

User Comments

“I often use the doubler on vocals and even on instruments, like electric guitars. You can get some pretty cool effects with it”

Ryan Nasci- Producer/Engineer: Tony Maserati, Jon Castelli, Isa “Machine” Summers, Tyler Johnson

“The automatic doubling process is saving me half a day per song!!”

Michael Hagel- Composer, Producer: Roger Whittaker, Vicky Leandros

“Doubling is the secret weapon for the modern pop and hip hop vocal sound, and Revoice Pro crushes in that area.”

Howie Miura- Producer

Warp

Warp processing In Revoice Pro 4 makes it easy to select and manually manipulate the timing and pitch of your audio whilst maintaining the highest audio quality. Get creative whilst improving or altering the pitch and timing of solo or guide tracks using an easy to use graphical interface.

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 are 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 available 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.

User Comments

“I am getting the job done just as fast, if not faster than using the two most popular tuning programs with better results. I like the way your software tracks the performance and I don’t get the crappy artefacts I sometimes get with the other software”

Jesse Zito

“The interesting thing is the authenticity issue – pitch correction and all the issues and press that surround it. One authentic take and then just tune it a little bit rather than just putting it together and patching together this word and that word. Just because they’re in tune, that’s probably a less authentic version in my opinion. So in a way, ReVoice Pro can actually give a more authentic vocal..”

Steve Williams- Lisa Stansfield, Sting, The Human League, Gary Barlow

Revoice Pro 4.4.1.11

April 14, 2022

Support for Apple Silicon

What’s new in version 4.3?

SmartAlign

Revoice Pro 4.3 is the first product to feature SmartAlign, our new technology which intelligently uses the presence of audio in your Dub track, instead of the Guide, to decide when an alignment should start and end. This is a huge timesaver as you can now transfer whole complex vocal arrangements into Revoice Pro and SmartAlign will calculate which section of the guide track your dubs should be aligned with. No more need for any manual pre-editing, let Revoice Pro 4 do all the hard work for you.

Logic ARA Compatibility

ARA or Audio Random Access is a revolutionary audio plug-in extension that enables unprecedented instant communication between ARA-enabled plug-ins and DAWs. There is now an ARA2 version of the Revoice Pro 4 Link AU plugin which enables your audio to be instantly captured, processed and returned to Logic Pro. Using Revoice Pro 4 with Logic Pro has never been easier, faster or more intuitive.

Improved Pro Tools Link & Quick Plugins

In Pro Tools, Revoice Pro 4 uses Audiosuite plugins to import and export your audio quickly and easily. With 4.3, we’ve updated the Quick APT and Quick Doubler plugins so you can save time by selecting processing presets without opening the main Revoice Pro 4 application. In addition, the Revoice Pro 4 Link plugin has been improved, so now you can create a Revoice Pro session which can be saved and reloaded to keep your adjustments and edits for future use. It’s also now possible to capture audio files and create processes from within the Link plugin too.

Two Activations Per License

A frequently requested feature in the past, Revoice Pro 4.3 now comes with two activations per license, so you can use the software on any two machines at the same time. You asked, we delivered.

Sync Points

If you run into complex alignment problems, Revoice Pro 4 has some advanced editing tools to solve tricky issues fast. Sync Points are user-defined target points on your guide and dub tracks which VocALign will try to ensure remain in sync when processing. Sync Points were included in Revoice Pro 2 but have been improved and re-added to this latest version of Revoice Pro.

More Great New Improvements in Revoice Pro 4.3 ….

Legato Audio Support

Pitch can be used to help the time alignment, this can be useful in legato audio as energy-based alignment may not be able to find the features it needs to accurately align your audio.

Offset Indicators

Blue lines are displayed on the guide and dub tracks. The lines move with the mouse pointer and show the corresponding position in the tracks calculated by the APT.

What’s new in version 4.2?

Automatic Scale Detection

The Warp function menu now includes the option to ‘Detect Scale’. When applied, Revoice Pro 4 will analyse the selected audio, determine the musical scale and only notes from that scale will appear on the left-hand side vertical bar when editing. Then once a musical scale has been set, corrected notes will snap to the available pitches.

Warp Improvements

• You can now adjust the part of note used to calculate the average pitch, this is especially useful when there are significant pitch deviations within a note which you don’t want to take into account
• You can now slip the start and end of notes
• Preset for Bass instruments
• Streamlined Warp editing tools and context menu to speed up your workflow

Formant Shifting

Formants are the harmonic frequencies which are present in the human voice. With Revoice Pro 4.2 it’s now possible to shift the formants of a performance to change its timbre or colour without affecting the pitch or timing.

Other Significant Changes

• Internal signal processing is now performed using 32 or 64-bit float values.
• Revoice Plug-ins will support audio with levels greater than 0dB (If supported by the DAW)
• ARA is now faster with larger sessions
• Streamlined Warp editing tools and context menu
