Halo Upmix.
Turn stereo into natural 5.1, 7.1 or 3D surround with real-time spatial analysis.

Overview
Stereo into immersive surround.
Halo Upmix converts stereo material into 5.1, 7.1 and 3D surround by analysing the spatial cues already in the mix, spreading the sound naturally without adding reverb or delay. Neural-network dialog extraction keeps the centre channel clean, while full channel-balance and low-frequency controls shape the result. An Exact mode preserves a downmix-safe result, and an optional 3D extension adds Dolby Atmos and Auro-3D.
