Halo Upmix

 

 

From naturally extracted and expanded soundscapes to full cinematic big-stage enhancement, Halo upmix delivers with intuitive ease, all the control you need to fine-tune your surround mix to perfection. With unique centre 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 has released a very professional product with Halo right from the onset... It was quite astonishing how extreme the surround image could be; yet the downmix was almost identical to the original."

Audio Media International | Simon Allen

 

 

 

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 panorama.

 

Detailed Centre Channel Control

 

Centre channel extraction and control is 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. Colour can additionally be used to indicate the speaker source for audio in any position, clearly indicating cases including phantom vs hard centre predominance etc.

9.1 Optional Extension (7.1.2 Dolby Atmos® bed track-compatible upmix)

 

 

 

 

 

The 9.1 extension introduces additional vertical controls via an expanded user interface including control over Ltm and Rtm 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 9.1 option is suitable for numerous applications including sound design, film score, restoration & archive, music and atmospheric soundscape production.

The Halo Upmix 9.1 Extension currently supports Avid Protools (AAX) & Steinberg Nuendo (VST3) for Windows and OSX.

Expert Surround-to-Stereo 

Halo Downmix provides a highly creative solution for precise downmixing of feature-film or 5.1 mixes to stereo. Intuitive, visual controls for relative levels, timing, and direct vs. ambient sound balance allow uprecedented fine-tuning, delivering accurate downmixes that are no longer limited by typical in-the-box coefficients-based processes.

A standard downmix is usually generated by simply mixing together the surround output according to standard downmix coefficients, however, this can often lead to unsatisfactory results, particularly if legacy upmix practices have been used to generate the original surround mix. Halo Downmix can be quickly employed to mitigate these issues eg. controlling excessive diffuse sound from added artificial reverberation, or removal of delay artefacts introduced in the rear channels.

Halo Downmix can be quickly deployed to produce a more controlled, coherent stereo mix.

Typical applications include:

• Stereo Mix production for Television within a Surround workflow.
• Rapidly producing a controlled, precise stereo downmix of a 7.1 feature film.
• Generating a stereo mix from surround where no stereo recording exists.
• Producing stereo interim listening mixes in a surround workflow.

 

Fine Tune Existing Surround material

Adjust existing 5.1 or 7.1 mixes in surround-to-surround mode. Levels of individual channels, and balance of direct vs. diffuse sound can be adjusted to fine tune or re-balance existing surround audio where access to the original mix is not possible.

 

Parallel Surround/Stereo Downmix workflow

Halo Downmix can also be used in conjunction with the included Receive plug-in to enable a parallel surround/stereo workflow.

This workflow allows for rapid A/B listening checks between surround and stereo downmix.

Applications include:

• Optimising a surround mix for better stereo downmix (standard coefficients)
• Harmonising surround and stereo experiences, delivering a separate downmix
• Harmonising surround and stereo to produce a modified surround mix and stereo downmix
