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 to perfection. With unique centre channel management, including switchable dialog extraction, Halo Upmix is perfect for all types of production from archive restoration and TV through to the 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, coherent spatial upmix, preserving the character of the original audio without adding any artificial reverb, chorus or delays.

With the 'Exact' control engaged, Halo Upmix can be used with confidence that the original source integrity is precisely preserved in the downmix.

Details

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.

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 transforms time intensive workflows and improves output quality with ease.

For Film & Sound Design:

With powerful control accessing every dimension of the upmix, Halo is indispensable for upmixing original and vintage scores - right up to Dolby Atmos and Auro 3D with the 3D Immersive extension.
