- About Us
From naturally extracted and expanded soundscapes to full cinematic big-stage enhancement, Halo upmix delivers with intuitive ease, all the control you need to fine-tune your surround mix to perfection. With unique centre channel management, including switchable dialog extraction, Halo is perfect for all types of production from archive restoration and TV through to the full 7.1 Feature Film experience.
"From the get go, Nugen Halo provides fast easy and clear up mixing on all my fx, bg and mx stems that need that surround push. The interface is elegant and the presets make even the most novice user feel at ease"
William Storkson | AudioSFX
Powerful real-time analysis of the original stereo material identifies and extracts locational cues, to naturally extend the panorama - without the introduction of any artificial reverberation, chorusing or delay into the downmix - leaving the inherent character of the original source intact.
Because Halo generates a coherent spatial sound, you can be assured of a high-quality downmix. The 'exact' mode function ensures ultimate downmix performance where, as in TV re-purposing for instance, maintaining the relationship between the original, upmixed and downmixed versions is imperative.
For those situations that require an immersive cinematic dynamic, full control is available of all the relative surround balances, allowing any surround upmix to be crafted for a perfect blend into the complete 7.1 panorama.
Detailed Centre Channel Control
Centre channel extraction and control is provided for in a separate 'advanced' panel for use when dealing with intricate mixes, where no access to the original stems is available, offering unparalleled control - including neural network based dialogue 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 etc.

Jacques Boulanger | Creative Audio Post
"we're now using Halo Upmix for any film or television project in which we want to create a highly natural-sounding 5.1 upmix for home and theatrical surround audiences... At Creative Audio Post, we're dedicated to ensuring that every sound element contributes to a production's overall emotional soundscape, and Halo Upmix has become an essential part of our toolkit. "
Mike Wabro | Audioinsight LTD
"I have been using [Halo] at every possible opportunity. The way it processes stereo sounds directly into 5.1 or larger multi-channel surround arrays is astounding. I have tested all the other plug-ins that offer this functionality, & for me Halo wins hands down. "
Michael Truman | Hybrid
Composer / Producer
"Halo is quite simply magnificent. After using the competition's plugins and then replacing it with Halo, the difference is like night and day. I've no idea what kind of algorithm you guys use but I'd like to buy it lunch and possibly go for drinks afterwards. Essential if you mix in surround. "
Terrance Dwyer | Owner | Mixers Hollywood
"At Mixers, music is usually delivered to us as mixed, stereo files. We use the Halo upmixer on all of our mixes to gently spread the stereo files into the 5.1 spectrum. We also do this with all stereo backgrounds. Unlike the previous plugin we used for this purpose which seemed to wash out 'localized' instruments, Halo allows us to do just enough to create a faithful, convincing upmix. We've come to expect a lot from Nugen and Halo delivers."
