NUGEN Audio Halo Downmix With 3D Immersive Extension

Precision downmix and surround re-balancing from 5.1, 7.1 or Dolby Atmos.

Halo Downmix completes your surround toolset enabling precise surround balancing, mix monitoring and sophisticated stereo fold-down. The glue that brings your workflow together, allowing you to deliver in surround and stereo with ease and without compromise.

Produce better downmixes and enhance the downmix compatibility of your surround mixes. 5.1, 7.1, advanced and compact interfaces perfectly designed for the task in hand, maximising screen real estate. Multiple monitoring modes, quick mute and solo controls promote rapid assessment and critical listening tests. Halo Downmix is the ideal complement to any surround workflow.

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.

Halo Downmix Includes

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
