- 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.
"HALO was used in two recent game cinematics - Fallen Empire received 'Best Trailer' award at E3 in Los Angeles, and Dishonored was 2nd. Both trailers were mixed with Halo as our upmixer. "
Gary Zacuto | Shoreline Studios
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.

Tony Friedman | Outpost Sound
"Almost everything I mix requires 5.1 delivery, but all of my music comes to me in stereo. That's why it's so critical to have a company like NUGEN. Halo is a truly musical sounding upmixer with an easy to use interface that gives you the control you need to fine tune your sound. Get Halo today. You won't be sorry."
Mike Aiton | Mikerophonics
"I used NUGEN's up mixer in the latest Harrods cinema commercial mix. NUGEN's unique amount of control with its focus, divergence & front/back fade gave me the ability to dig in and control the problems to get the best result. Happy ears indeed! I also used the NUGEN upmixer to create a better surround fx mix. Simple but powerful. A new go to plugin! "
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. "
Audio Media International | Simon Allen
"NUGEN Audio has released a very professional product with Halo right from the onset... It was quite astonishing how extreme the surround image could be; yet the downmix was almost identical to the original."
