A significant upgrade of the Halo Upmix software for taking stereo up to surround audio is being showcased. Available in Avid AAX, VST and AU formats, Halo Upmix automates the creation of a stereo-to-surround, downmix-compatible upmix with centre-channel management and spatial density controls.
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 dialogue isolation, according to Nugen.
The latest version of Halo Upmix also adds a brand-new set of algorithms for upmixing from multichannel audio to higher channel counts, including LCR to 5.1, 5.1 to 7.1, and 7.1 to 9.1.
The 9.1 option allows the introduction of vertical positioning into the upmix, generating a 7.1.2 Dolby Atmos bed track-compatible upmix. This capability provides users with greater flexibility for high-quality archival restoration, content repurposing, post-production and sound design,
