Expert Surround-to-Stereo

Simply using standard downmix coefficients can often lead to unsatisfactory results, particularly if legacy upmix 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 reverberation, or removing delay artifacts introduced in the rear channels.

Fine-tune Existing Surround Material

Adjust existing 5.1 or 7.1 mixes in surround-to-surround mode. Levels of individual channel 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.

3D Immersive Extension

The optional 3D Immersive Extension for Halo Downmix adds capability for downmixing 7.1.2 Dolby Atmos bed tracks to 7.1, 5.1 and stereo.

Parallel Workflows

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

Flexible, Intuitive Interface

Halo Downmix provides a highly creative solution for precise downmixing of 7.1 or 5.1 mixes to stereo. 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 customizable interface includes both 7.1 & 5.1 modes, and 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 visualization of surround energy distribution.
