Multi-channel audio gets down

Making its European debut is Halo Downmix, designed for the precise downmixing of feature film and 5.1 mixes to stereo. Nugen said the product delivers accurate downmixes that are no longer limited to typical in-the-box coefficient-based processes. It allows for unprecedented adjustment, and provides visual controls for relative levels, timing and direct vs ambient sound balance.

Dialogue level can be maintained effectively with phantom centre ratio controls, and excess ambient sound from rear channels can be managed easily.

Nugen said low frequencies can also be regulated to ensure appropriate levels in downmix, and timing artefacts in surround channels introduced by legacy upmix practices are now easy to fix, either manually or by using the Halo Downmix auto detection functionality.

Halo Downmix introduces a surround-to-surround mode for adjusting existing 5.1 or 7.1 mixes for better downmix compatibility or rebalancing of the surround mix.
