Halo Upmix Includes
Powerful real-time analysis of the original stereo material
identifies and extracts locational cues, to naturally extend the
panorama - without the introduction of any artificial reverberation,
chorusing or delay into the downmix - leaving the inherent character of
the original source intact.
Because Halo generates a coherent spatial sound, you can be assured
of a high-quality downmix. The 'exact' mode function ensures ultimate
downmix performance where, as in TV re-purposing for instance,
maintaining the relationship between the original, upmixed and downmixed
versions is imperative.
For those situations that require an immersive cinematic dynamic,
full control is available of all the relative surround balances,
allowing any surround upmix to be crafted for a perfect blend into the
complete 7.1 panorama.
Detailed Centre Channel Control
Centre channel extraction and control is provided for in a separate
'advanced' panel for use when dealing with intricate mixes, where no
access to the original stems is available, offering unparalleled control
- including neural network based dialogue extraction.
Powerful Spatial Analysis
Halo also includes a powerful spatial analysis view, intuitively
showing the energy distribution of the upmixed panorama. Colour can
additionally be used to indicate the speaker source for audio in any
position, clearly indicating cases including phantom vs hard centre
Halo Downmix Includes
Expert Surround-to-Stereo Halo Downmix provides a highly creative solution for precise
downmixing of feature-film or 5.1 mixes to stereo. Intuitive, visual
controls for relative levels,
timing, and direct vs. ambient sound balance allow uprecedented
delivering accurate downmixes that are no longer limited by typical
A standard downmix is usually generated by simply mixing together the
surround output according to standard downmix coefficients, however,
this can often lead to unsatisfactory results, particularly if legacy
upmix practices have been used to generate the original surround mix.
Halo Downmix can be quickly employed to mitigate these issues eg.
controlling excessive diffuse sound from added artificial reverberation,
or removal of delay artefacts introduced in the rear channels.
Halo Downmix can be quickly deployed to produce a more controlled, coherent stereo mix.
Typical applications include:
• Stereo Mix production for Television within a Surround workflow.
• Rapidly producing a controlled, precise stereo downmix of a 7.1 feature film.
• Generating a stereo mix from surround where no stereo recording exists.
• Producing stereo interim listening mixes in a surround workflow.
Fine Tune Existing Surround material
Adjust existing 5.1 or 7.1 mixes in surround-to-surround mode. Levels
of individual channels, and balance of direct vs. diffuse sound can be
fine tune or re-balance existing surround audio where access to the
mix is not possible.
Parallel Surround/Stereo Downmix workflow
Halo Downmix can also be used in conjunction with the included Receive plug-in to enable a parallel surround/stereo workflow.
This workflow allows for rapid A/B listening checks between surround and stereo downmix.
• Optimising a surround mix for better stereo downmix (standard coefficients)
• Harmonising surround and stereo experiences, delivering a separate downmix
• Harmonising surround and stereo to produce a modified surround mix and stereo downmix
