ISE: Amadeus Announces HOLOPHONIX 1.5 Release, to be Available in March 2020

Amadeus HOLOPHONIX v1.5

Amsterdam – ISE – February 10, 2020 — Unveiled in 2018 at the Frankfurt Prolight + Sound trade show, and commercially available since January 1st, 2019, the HOLOPHONIX spatial sound processor continues to be updated and enhanced, according to requests and needs expressed by its users.

Developed with several musical, theatrical and scientific institutions, the HOLOPHONIX processor was designed 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.

“We released about ten updates over the last 18 months, answering requests of our extremely proactive users, who never stop sending us feedback. The forthcoming 1.5 version is a more structural update. It includes a complete overhaul of the graphical user interface (GUI) and a totally revised communication bridge between servers and applications, optimizing high-speed transmission of OSC messages. Rewriting our graphical interface from the ground up, according to new Web technology standards, ensures optimal performances with today’s tools, with deep scalability and flexibility for the future,” says Johan Lescure, HOLOPHONIX Chief Technology Officer at Amadeus.

“In addition, a new application, HOLOPHONIX Updater, is now available. It allows the users to download updates themselves, to upgrade their station in perfect autonomy. Audio core performances have been optimized as well, and the user can still adapt the processor to its use, by choosing between CPU load and global latency (which can be as low as 1.90ms),” Johan Lescure specifies.

Version 1.5 includes new encoders and source formats developed by STMS, to ensure maximum compatibility with different Ambisonics capture tools.

This new version also includes an equalizer, offering 5 PEQ plus high-pass filters, and low-pass filters. This equalizer is available for each virtual source and each physical (Dante) output, as well as spatialization buses, offering more versatility and features to the processor.

The HOLOPHONIX processor is also now compatible with the em32 Eigenmike microphone, developed by mh acoustics. It includes 32 microphone capsules, to capture soundstages in the HOA (Higher Order Ambisonics) 4th order format. The processor is also compatible with the ZM-1 microphone developed by Zylia. ZM-1 includes 10 microphone capsules, to capture soundstages in the HOA 3rd order format.

The processor already allows the processing of 1st order Ambisonics streams in A-Format and B-Format. It can thus process natively raw signals available directly at the output of Ambisonics microphones (A-Format) like Sennheiser AMBEO, SoundField ST250, ST450 or SPS200, RØDE NT-SF1, DPA-4 or Oktava MK-4012. It can also process a generic format source (B-Format) with parameters available to offer compatibility with various formats and standards (FMH, ACN, as well as normalizations FuMa, MaxN, and SN3D).

An offline editor software, HOLOPHONIX Designer, is also available, including a binaural pre-rendering function. This application, available on Windows and macOS platforms, will integrate all the graphical functionalities available inside the HOLOPHONIX processor, with a binaural rendering engine to ease project pre-production while listening on headphones.

The processor integrates new ‘MicTree’ virtual objects (or sources), to process a main ‘microphone tree’ more easily. A single ‘MicTree’ object can include 1 to 128 microphones. The ‘Mics’ window allows the user to define the real position of the microphones, and if appropriate, to automatically realign each cell, in time (delay) and in intensity (level). Any ‘MicTree’ source captures the integrality of the soundstage, without applying any specific processing to the signal.

Also new for the 1.5 update, the HOLOPHONIX processor is now equipped with a new decoder, called LBAP (Layer-Base Amplitude Panning). LBAP is an amplitude panning algorithm, optimized for tridimensional setups based on several layers (with a different number of speakers for each). This algorithm works by selecting a speaker pair on each of the layers surrounding the source, applying an amplitude panning on each pair, then completing a level ponderation between the two layers. It ensures better results than VBAP (Vector-Base Amplitude Panning) for cube-shaped configurations.

“Finally, HOLOPHONIX integrates the first software features leading towards using the processor (and thus, possibly, mixing) in Virtual Reality. The processor is already compatible with the Oculus Quest headset, to more easily manipulate sources from a virtual and tridimensional room. Our users are looking for solutions to control and move sources via new interfaces and/or tools, more natural and more universal than traditional 2D-control surfaces. This innovative ‘VR’ approach in the HOLOPHONIX 1.5 update is a first part of the answer, which we will develop and extend,” concludes Johan Lescure.
