01Overview

Halo Upmix is built for producers who need a surround version of stereo material. Its real-time analysis looks at the original stereo program and extracts locational cues to extend the panorama. A spatial analysis view shows how energy is distributed across the upmixed field, and an advanced panel gives separate control of the centre channel for intricate mixes.

Natural Panoramic Extension for Stereo-to-Surround Mixing

Halo analyzes the original stereo material and extracts locational cues to widen the panorama into a surround field. NUGEN Audio says the process adds no artificial reverb, chorus or delay, so the character of the source stays intact.

The developer notes that Halo generates a coherent spatial sound, which supports a high-quality downmix. An exact downmix mode keeps the relationship between the original, upmixed and downmixed versions, a priority in TV re-purposing. Full access to all surround balances lets you shape the upmix for a blend into the complete 7.1 panorama.

Centre Channel and Dialogue Control

The advanced panel handles centre channel extraction and control. This is useful when no access to the original stems is available. Halo includes neural network dialogue extraction, a switchable option, along with low frequency energy dispersal and clear control over phantom versus hard centre.

The spatial analysis view shows the energy distribution of the upmixed panorama. Colour can indicate the speaker source for audio in any position, which makes phantom and hard centre predominance easy to read. A full LFE control option is also included.
