Nugen Audio Announces Halo Upmix

Nugen Audio has announced Halo Upmix, a new software product for Mac and PC, which allows upmixing stereo audio to 5.1 / 7.1 surround in television and film productions. Available in Avid AAX, VST, and AU formats, Halo Upmix automates the creation of a stereo-to-5.1/7.1 downmix-compatible upmix with unique center channel management, and spatial density controls.
Nugen Halo Upmix Interface
Halo Upmix provides a new solution for upmixing stereo audio to surround 5.1 or 7.1 when there is no access to the original multitrack recording. This is particularly true when downmix compatibility is critical; for instance, when consumer set-top boxes play out stereo downmixed from broadcast 5.1. Combining several technologies including frequency- and time-domain energy distribution and neural network artificial intelligence, Halo Upmix enables producers to target various upmix goals including full stable surrounds, exact downmix matching, and/or full dialog isolation. In addition to stem and group upmixing, producers can use Halo Upmix’s center channel control and management to fine-tune a surround mix and to create intricate mixes when there is no access to the original stems. The solution’s detailed center channel control includes NUGEN Audio’s proprietary neural network-based dialog extraction.

In addition, Halo Upmix performs real-time analysis of the original stereo material by identifying and extracting locational cues. This enables the solution to extend the sound panorama naturally without introducing artificial reverberation, chorusing, or delay into the downmix. In this manner, operators can preserve the inherent character of the original source material when repurposing stereo for cinematic release. Halo Upmix is downmix-safe, providing coherent spatial sound to assure quality downmix performance for work in which correlation between original, upmixed, and downmixed versions is imperative, such as TV repurposing. Also, full control is available for all relative surround balances — up to 7.1 — for those applications that require a more immersive, “big cinematic sound” experience.

In addition, Nugen Audio is announcing support for Leq(m) loudness measurement as a free update for its recently announced VisLM-H2 loudness meter, LM-Correct 2 loudness quick fix tool, and LMB processor for batch loudness analysis and correction on multiple files. Leq(m) support provides mission-critical capabilities for audio professionals who work on theatrical trailer production and will complement the extensive ITU loudness measurement capabilities already available in NUGEN Audio loudness products.

Future Filmmaking is quite familiar with Nugen from our sister publication, Future Music. This is a great extension of their proprietary technology and it’s definitely worth a look

Nugen Audio’s Halo Upmix costs $499 and will be available shortly.
