Version: 1.8.0

Welcome to 1.8.0

HOLOPHONIX 1.8.0 introduces many interface changes, to improve workflow and user experience. This version is also packed with several bugfixes and performance improvements.

Quick Tour

Welcome to 1.8.0. Some key features of the software have changed place, and here is a quick summary of where to find them.


The "What's New in HOLOPHONIX 1.8.0" video is coming soon to our Youtube channel.

Where to find Views, Tabs and 3D Parameters


Feels familiar? Yes, this is a view of version 1.7.0. We realized that the interface was beginning to look crowded and we decided to reduce the amount of icons displayed by using brand new drop down menus. First, the tabs on the left side are now accessible in the new Windows drop down menu, as shown in the first image:


The Views (orientation of the 3D Venue Camera) are now accessible from the new Camera drop-down menu:


Finally, the 3D parameters icons are now stacked in the new Venue Parameters window.


New Draggable and Resizeable windows

One of the huge innovations of 1.8.0 is that you now have the freedom of positioning windows where you like them. You can have a maximum of two windows open at the same time : one is either the Inspector or the Venue Parameters, and the other can be any of the rest. Use the new arrow icons to either dock the windows, bring them fullscreen or free them.



If you want to see the Venue Parameters window, make sure to unselect every element (source or speaker) or else, only the Inspector window will show.

Import 3D models of your venue

If you have a 3D modelization of your venue in the .glb format, you can import it in the Venue Parameters window ! By default, we have included a 3D view of the Avignon’s Cour d’Honneur so that everyone can experience this new feature. You can hide it in the same menu by clicking the eye icon.

Also, feel free to try the new Light Theme Mode... It has proven useful under the sun of Avignon !



The majority of the changes concern the interface, with the major addition being the new support for 3D modelizations directly inside the 3D Venue.


Be sure to make a Backup of your old projects before opening them with the new HOLOPHONIX version
