Amadeus Unveils New HOLOPHONIX Immersive Processors at ISE 2023 and a 2.1 Software Release

Amadeus announces new HOLOPHONIX 128 and 64 hardware processors, offering respectively 128 and 64 outputs, as well as a new software update, available for all HOLOPHONIX processors and Native App


Barcelona, SpainISE – January 31, 2023 – At the 2023 Integrated Systems Europe (ISE) conference in Barcelona, Amadeus (Booth 7F225) has debuted a new 2.1 software version for its immersive platforms – HOLOPHONIX Servers, and the HOLOPHONIX Native app for macOS – plus two new configurations for its hardware processor offering 128 outputs and 64 outputs. The new 2.1 software update version is free and will be available on February, 1 at

The new HOLOPHONIX hardware configurations are available for order now and feature redesigned rear panels with Neutrik-housed connectors integrated into the aluminum chassis, including one powerCON mains connector, three etherCON connectors for remote control and Dante redundant protocol, as well as HDMI and USB 3.2 connectors for service. The updated HOLOPHONIX processor models are 1.6x faster than the previous model. The HOLOPHONIX 128 model offers 128×128 I/O at 96 kHz in Dante AoIP format, while the new HOLOPHONIX 64 model offers 128 inputs for 64 outputs at 96 kHz in Dante AoIP format.“Machined in three dimensions from a solid aluminum block – taking more than twenty hours to complete – the new HOLOPHONIX processor enclosure embodies all the technicality embedded and hidden within this unique tool,” states Gaetan Byk, Amadeus CEO.

“We designed some interesting features for the Wave Field Synthesis (WFS) algorithm over the last months, which figure among the most interesting algorithms built-in HOLOPHONIX, used in 90% of the systems that we deploy,” says Gaetan Byk.

“Recent work conducted at IRCAM helped us extend and improve our Wave Field Synthesis rendering engine.

Originally restricted to 2D dense linear arrays of loudspeakers, the WFS approach has been generalized and is now compatible with arbitrary 3D loudspeaker layouts. This features several optimizations for large arrays, or linear arrays with large spacing in-between loudspeakers, as well as 3D dome-like speaker layouts,” comments Thibaut Carpentier, Researcher at IRCAM, Lead Developer, and Head of the SPAT project.

“With immersive speaker systems, users can now create virtual sounds anywhere in 3D space; full-3D WFS gains and delays are computed in real-time, generating a convincing sound field that overcomes limitations of other techniques such as Ambisonics,” adds Thibaut Carpentier.

The new HOLOPHONIX 2.1 Update features among other improvements a new 3D-native computation of gains and delays for the WFS algorithm, a new ‘Minimal Delay’ mode, and a new parameter called LSO (Large Stage Optimizer) designed to optimize intelligibility for spectators sitting in the very first rows.

“The ‘Minimal Delay’ parameter option is only available for the Wave Field Synthesis algorithm. When disabled, the WFS bus calculates the source’s delays and gains related to their real position from the speaker array. Thus, moving a source away from the speaker array increases the overall delay and latency. When enabled, the bus calculates the source’s delays and gains but subtracts the distance to the nearest speaker, resulting in lower latency” says Adrien Zanni, Researcher and Developer at Amadeus for the HOLOPHONIX project.

“The ‘Large Stage Optimizer’ (LSO) was originally designed for the Avignon Palace of Popes Cour d’Honneur at the Avignon Festival which features a very large 40-meter wide stage. The LSO function in version 2.1 offers an ‘intelligibility enhancement’ for spectators sitting in the very first rows, especially those who are placed on the opposite side of the on-stage performers. Based on the WFS pure rules, if a comedian, for example, performs on the very left front of the stage, the spectator placed 40 meters away, on the right of the audience will hear a very low reinforcement level because of the WFS’ natural gain attenuation,” adds Adrien Zanni.

Additional Features for the HOLOPHONIX 2.1 Update:
  macOS Ventura compatibility for HOLOPHONIX Native
  Apple Silicon (ARM architecture) optimization for HOLOPHONIX Native
  New ‘Minimal Delay’ bus function for WFS
  New ‘Large Stage Optimizer’ (LSO) function for WFS
  New interfaces for source and bus creation
  New function enabling automatic bus creation from predefined speaker groups
  New function offering an automatic suggestion of the HOA order based on the number of speakers
  Improvement of the presets loading
  Graphical enhancements on File, and Display menus
  Bug corrections
