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

Revoice Pro 4 and APT Controls

Revoice Pro 4 and New Process Controls

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 Warpfunction 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:

Revoice Pro 4 APT Controls

• 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
