Halo Downmix

Decisive downmixing

Complement your workflow

Halo Downmix enables precise downmixing, 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, with an interface perfectly designed for the task in hand. Halo Downmix is the ideal complement to any surround workflow.

Precise control

Streamline your workflow with versatile downmix balancing and mix monitoring.

• Downmix surround-to-stereo
• Fine-tune surround-to-surround
• Regulate low frequency content
• Maintain dialog clarity
• Control excess ambient sound
• Remove delay artefacts
• Monitor surround and stereo in-place

Expert surround-to-stereo

Using standard downmix coefficients can sometimes lead to unsatisfactory results, particularly if legacy upmixing practices were used for the original surround mix. Halo Downmix quickly mitigates these issues and produces a more coherent stereo mix, controlling excessive diffuse sound from artificial reverb, and removing delay artefacts from the rear channels.

Fine-tune surround-to-surround

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

3D Immersive Extension

The 3D Immersive Extension option for Halo Downmix adds the ability to downmix from 7.1.2 – the format used for Dolby Atmos bed tracks.

Parallel workflows

Halo Downmix can also be used in conjunction with the NUGEN Receive plug-in (included) to enable a parallel surround/stereo workflow. This allows for rapid A/B checks between the full surround mix and the stereo downmix.

Flexible, intuitive interface

Halo Downmix provides a highly creative solution for precise downmixing. Intuitive, visual controls for relative levels, timing, and direct/ambient sound balance allow unprecedented fine-tuning, delivering accurate downmixes no longer limited by typical in-the-box processes.

Halo Downmix’s highly customisable interface includes both advanced & compact modes, with quick-select ‘in-place’ monitoring of stereo and surround signals, as well as quick linked solo and mute functions at every stage, and clear visualisation of surround energy distribution.

Typical applications

• Surround-to-stereo downmixing
• Surround re-balancing and fine-tuning
• Simultaneous surround/stereo workflow
• Surround restoration
• Stereo production within a surround workflow
• Maintaining dialog clarity in surround
• Removing rear-delay artefacts from legacy upmixing practices

Product specifications

Available formats

Supports 64bit AAX , VST3, AU and AAX AudioSuite. Halo Downmix requires a surround-compatible plug-in host (5.1/7.1) such as Pro Tools HD.

NUGEN Audio is in the process of phasing out some older plug-in formats. Our most recently updated products no longer support RTAS or VST2. Customers who still wish to use RTAS or VST2 can download a legacy installer from the Build Archive.
