Holophonix Ultra

Advanced and Powerful Spatial Audio Processing

OVERVIEW
The Funktion-One approved Holophonix Ultra platform is one of the most advanced and powerful spatialisation processors available.
The Holophonix spatial audio platform meets our extremely high audio standards and supports free positioning of loudspeakers. Funktion-One spatial audio systems can be designed for any space and existing stereo systems can be augmented with additional loudspeakers rather than requiring a complete redesign. It supports true object-based mixing, multiple 2D and 3D rendering approaches, and processor-based operation for low-latency, high channel count deployment. It is built around practical live workflow as well as advanced research, with algorithms developed through IRCAM-linked research and hardware options that support Dante-based I/O.

Output standards / loudspeaker positioning:
Free loudspeaker positioning to fit any custom loudspeaker layout from stereo to full 3D sphere (azimuth and elevation).
Outputs can also be configured to standard output formats (for example to record an automatic downmix of the performance):
- Channel-based setup:
- any ITU standard (e.g. 5.1, 7.1, 22.2, etc.),
- Stereo panning,
- AB/XY microphone simulation for more realistic results,
- Binaural
Reverberation:
- 3D-immersive algorithmic reverberation
- Object-based simulation and independent control of direct sound, early reflections and late reverberation parameters
- Automatic level option based on source positioning and distance
- Model based on perceptual studies of distance
Processing options:
- Trim (-80, +30dB) and Gain (-60, +12dB) adjustments for sources, buses and master
- Adjustable delay (from 0 to 5000 ms) on sources, buses and outputs
- Equaliser and dynamic processing options on each source, bus, with fully adjustable bands and shelves available
- Equaliser for each reverberation stage
- Equaliser available on each audio output (loudspeaker)Loudspeaker gain and delay adjustment on each spatialisation bus, individually(with automatic computation mode based on loudspeaker positioning)
Monitoring
- Integrated binaural monitoring of sources and the loudspeaker setup
Subwoofer management:
- LFE channel with adjustable HPF filter (2nd order IIR filter, 12 dB/oct) and equaliser and dynamics processing.
- User-defined subwoofer buses, using any available algorithm
