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.

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.
