Expert surround to stereo

Simply using standard downmix coefficients can often lead to unsatisfactory results, especially if legacy upmixing practices were used for the original surround mix. Halo Downmix can quickly mitigate these issues and produce a more coherent stereo mix, for example, by controlling excessive diffuse sound from added artificial reverb or eliminating delay artifacts introduced in the rear channels.

Fine-tuning existing surround material

Adjust existing 5.1 or 7.1 mixes from surround to surround. Individual channel levels and the direct-to-diffuse sound balance can be adjusted to fine-tune or rebalance existing surround audio when the original mix is not accessible.

3D Immersive Extension

The new 3D Immersive Extension option for Halo Downmix adds the ability to mix Dolby Atmos 7.1.2 bed tracks to 7.1, 5.1, and stereo.

Parallel workflows

Halo Downmix can also be used with the included reception plugin to enable a parallel surround/stereo workflow. This allows for quick A/B listening checks between the full surround mix and the stereo downmix.

Flexible and intuitive interface

Halo Downmix provides a highly creative solution for the precise mixing of 7.1 or 5.1 mixes to stereo. Intuitive visual controls for relative levels, timing, and direct/ambient sound balance allow for unprecedented fine-tuning, providing precise mixes that are no longer limited by typical in-the-box processes.

The highly customizable Halo Downmix interface includes 7.1 and 5.1 modes, as well as advanced and compact modes, with quick-selection 'in-place' stereo and surround signal monitoring, as well as quickly linked mute and solo functions at every stage, and clear visualization of surround energy distribution.
