Halo Upmix

Full control, intuitive ease

From naturally extracted and expanded soundscapes to full cinematic big-stage enhancement, Halo Upmix delivers all the control you need to fine-tune your surround mix. With unique centre channel management, including switchable dialog extraction, Halo Upmix is perfect for all types of production from restoration to full 7.1 feature film experience.

An optional 3D extension adds Dolby Atmos bed track (7.1.2) and Auro 3D (7.1.4) compatibility, and Ambisonic outputs.

The Halo Upmix algorithms produce a natural upmix, preserving the original character without adding any artificial reverb, chorus or delays.

With the 'Exact' control engaged, the original source integrity is precisely preserved in the downmix.

Halo Downmix requires a surround-compatible plug-in host (5.1/7.1) such as Pro Tools HD.

Natural extension

Powerful real-time analysis of the original stereo material identifies and extracts locational cues to naturally extend the panorama, leaving the inherent character of the original source intact.

• Coherent spatial upmix

• Full access to surround balances

• Low frequency energy control

• Clear visual feedback

• Direct control over upmix parameters

• No artificial reverb, chorus or delays

• 'Exact' downmix mode with in-place audition

• Neural network dialog extraction

Powerful spatial analysis

Halo also includes a powerful spatial analysis view, intuitively showing the energy distribution of the upmixed panorama.

Colour can additionally be used to indicate the speaker source for audio in any position, clearly indicating cases including phantom vs hard centre predominance.

Downmix compatibility

Because Halo Upmix generates a coherent spatial sound, you can be assured of a high-quality downmix.

The 'exact' mode function ensures ultimate downmix performance in situations where maintaining the relationship between the original, upmixed and downmixed versions is imperative, for example in TV repurposing.

3D Immersive Extension

The optional 3D Immersive Extension introduces additional vertical controls via an expanded user interface including control over Ltm and Rtm placement for Dolby Atmos compatibility. 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 3D Immersive Extension is suitable for numerous applications including sound design, film score, restoration & archive, music and atmospheric soundscape production.

For Television

With surround delivery requirements becoming more and more common, Halo Upmix can be indispensable.

Providing sophisticated control including neural network powered dialog isolation Halo transfroms time intensive workflows and improves output quality with ease. Simply integrate it into your workflow and enjoy a great sound, without the hassle of tedious editing.

For Film & Sound Design

With powerful controls, Halo is indispensable for upmixing original and vintage scores - right up to Dolby Atmos and Auro 3D with the 3D Immersive extension.

Multiple instances in sound design and scores breath life into the sound in ways that delay and panning techniques can't approach - all with a solid reasurrance of a highly downmix compatible result.

With Ambisonic, Upmix also works in VR and game environments.
