Stereo to 5.1, 7.1 and 3D Upmixer
NUGEN Audio Halo Upmix allows users to Upmix to any multichannel format.
Halo Up Mix delivers all the control you need to fine-tune your surround mix to perfection with intuitive ease – From naturally extracted and expanded soundscapes to full cinematic big-stage enhancement. With unique center channel management, including switchable dialog extraction, Halo is perfect for all types of production from archive restoration and TV through to the full 7.1 Feature Film experience.
NUGEN Audio Halo Upmix Highlights
Natural Extension
Powerful real-time analysis of the original stereo material identifies and extracts locational cues, to naturally extend the panorama – without the introduction of any artificial reverberation, chorusing or delay into the downmix – leaving the inherent character of the original source intact.
Downmix Compatibility
Because Halo generates a coherent spatial sound, you can be assured of a high-quality downmix. The ‘exact’ mode function ensures ultimate downmix performance where, as in TV re-purposing for instance, maintaining the relationship between the original, upmixed, and downmixed versions is imperative.
Big sound
For those situations that require an immersive cinematic dynamic, full control is available of all the relative surround balances, allowing any surround upmix to be crafted for a perfect blend into the complete 7.1 panoramas.
Detailed Centre Channel Control
Centre channel extraction and control are provided for in a separate ‘advanced’ panel for use when dealing with intricate mixes, where no access to the original stems is available, offering unparalleled control – including neural network-based dialogue extraction.
Powerful Spatial Analysis
Halo also includes a powerful spatial analysis view, intuitively showing the energy distribution of the upmixed panorama. Color can additionally be used to indicate the speaker source for audio in any position, clearly indicating cases including phantom vs hard center predominance, etc.
Description
Optional 3D Immersive Extension
(7.1.2 Dolby Atmos® bed track-compatible upmix/Amisonic Output)
The 3D Immersive Extension introduces additional vertical controls via an expanded user interface including control over Ltm and Rtm placement for Dolby Atmos compatible placement. An additional real-time analysis view is also included for the vertical dimension, showing energy distribution of the output audio.
The enhanced upmix algorithm allows for simultaneous use of all the original features including dialog isolation and individual channel output control.
The Halo 3D option is suitable for numerous applications including sound design, film score, restoration & archive, music and atmospheric soundscape production. The Halo Upmix 3D Immersive Extension currently supports Avid Protools (AAX) & Steinberg Nuendo (VST3) for Windows and OSX.
