Amadeus Releases Major 1.7 Software Update for HOLOPHONIX

New software version of immersive spatial sound processor gets redesigned web-remote user interface plus many advanced features for better performance and faster workflow

Paris, France June 14, 2021 – Amadeus has released a major software update for the company’s HOLOPHONIX spatial sound processor. The version 1.7 software update features a new web-remote user interface completely redesigned from the ground up for better performance and a faster workflow, and includes a host of new features both powerful and useful for immersive creative projects. The new version 1.7 update is free to all current HOLOPHOPNIX users and is included with all new HOLOPHONIX hardware system purchases.

HOLOPHONIX immersive sound processors are installed and have been used for some of the world’s most innovative venues including Paris-based The Pantheon, Chaillot National Theater, La Scala, La Comédie Française, as well as the Beijing Stadium(China), The Lee Seok Young New Media Library in South Korea, ETH Zürich in Switzerland, and many others.

Developed with several musical, theatrical and scientific institutions, the HOLOPHONIX processor was designed by Amadeus in a collaboration with the STMS (Sciences et Technologies de la Musique et du Son), a laboratory founded in 1995 and hosted by the Institut de Recherche et Coordination Acoustique/Musique and affiliating the CNRS, Sorbonne Université, the Ministère de la Culture, and IRCAM around an interdisciplinary research theme dealing with music and sound sciences, and technologies.

Previously, the Wave Field Synthesis algorithm was restricted to linear speaker arrays with regular spacing between the transducers. With HOLOPHONIX 1.7, Wave Field Synthesis now also supports non-linear speaker arrays, including 2D surround setups. The algorithm can now control circular, rectangular, or curved-shaped loudspeaker layouts with non-uniform spacing,”says Thibaut Carpentier, Researcher at IRCAM, Lead Developer, and Head of the SPAT project.

The HOLOPHONIX built-in reverberation engine also offers new features, such as a new ‘Room Size’ parameter which lets you adjust the reverb effect more finely. Another useful feature built into this update is a per-speaker Equalizer,” adds Thibaut Carpentier.

The Equalizer offers 7 PEQ, plus high- and low-pass filters; similar EQ is also available on the reverberation busses.

  • Completely redesigned web-remote user interface offers enhanced workflow
