Paris, France (March 31, 2021)—French electronic music producer ÉléphantMat, the alter-ego of artist, producer and engineer Mathieu Rossier, recently recorded and streamed a live two-hour spatialized performance piece from the Grand Palais in Paris with a little help from Flux Immersive’s Spat Revolution plug-in.

Rossier is also founder of Des Sons Animés, a 32-channel spatial sound studio where he hosts live 3D spatialized audio streams via his Facebook page, streaming his Ableton Live screen and his live performance. Des Sons Animés is among the first private studios in France to utilize wave field synthesis in live musical applications. The studio is designed to virtualize a range of configurations, including object-based, Dolby Atmos, 5.1, 7.1, MPEG-H, ambisonic, Auro-3D and more.

With most venues shut down, Des Sons Animés teamed with promotors BNK to create Capture, a series of livestreamed immersive events performed and recorded in national heritage locations. For one recent Capture event, Rossier’s Des Sons Animés crew installed an 18-channel immersive system at the Grand Palais, where ÉléphantMat presented a live two-hour spatialized performance piece. Des Sons Animés recorded the multitrack audio in object-based format, remixing the soundtrack using binaural encoding with Spat Revolution.

“We placed 16 speakers in a circle around me at a diameter of eight meters (26 feet), with two subwoofers outside the circle,” Rossier explains. “Without an audience, we didn’t have to concern ourselves with acoustic treatment for the space, which was far too large to really address. The distance from the speakers provided me with a good level of monitoring and placement.”

Rossier sent sequences from Ableton Live directly to objects within Spat Revolution. “For this project, I knew I wouldn’t have any elevation, since all the speakers were mounted at the same level, so I used a 3D spatial partition, including elevation, which I then monitored in 2D on the Grand Palais setup. Spat enabled us to create two mixing streams, one for the studio monitoring and one for the stream’s binaural rendering.

“Once back in the Des Sons Animés studio, all I had to do was send the recorded session into Spat, with audio and data in OSC, and use Spat’s binaural rendering to lay it down to a two-channel mix for the video.”
