"Halo is a truly versatile upmixing plug-in. It can both be saintly and angelic, with the down-mix (from the up-mix) being virtually indistinguishable from the original; or you can take the safety catch off and you can let its Halo slip and go off-piste, and be highly creative and controllably imaginative with the up-mixing."

Mike Aiton | Mikerophonics


Natural Extension

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.


Downmix Compatibility

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.


Big sound

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.

"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. "


Gary Zacuto | Shoreline Studios


"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. "

"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-ings that offer this functionality, & for me Halo wins hands down. "


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."
