Opera Australia Uses IOSONO 3D Sound on ‘Die tote Stadt’ Production at the Sydney Opera House

Korngold’s opera “Die tote Stadt” shines in new splendour with leading 3D sound technology.

Korngold’s opera “Die tote Stadt” successfully premiered at the world famous Sydney Opera House with IOSONO 3D sound on June 30, 2012. The elaborate production by Opera Australia is breaking new ground as the orchestra’s music is streamed live to the Opera Theatre using IOSONO’s 3D sound technology. While the musicians are playing live in the neighboring studio, cinematic surround sounds fill the theatre bringing the performance to the audience and singers.

For “Die tote Stadt” IOSONO 3D sound creates a unique acoustical reproduction of the physically absent orchestra by building an acoustical hologram of the orchestra in one of the world’s most famous concert halls. This approach is a unique experience for the audience, as well as for the singers on stage, creating a fascinating interplay between the live-performance and the streamed orchestra in 3D sound. Tony David Cray, sound designer for the project and Head of Recording and Broadcast for Sydney Opera House, is happy with the results: “I am thoroughly impressed by how IOSONO allows to reproduce the body of the orchestra. The localization of every single instrument is stable throughout the theatre and the transparency is amazing. It’s a real game changer.”

To virtually bring the musicians to the opera stage and achieve a proper reconstruction of the orchestral body, IOSONO is using its audio processor and the d&b loudspeakers installed in the Opera Theatre. Olaf Stepputat, CEO of IOSONO, remarks: “We are very proud to be showing the capabilities of IOSONO in such an esteemed venue. The results are great – the sound is very clear and the transparency of the d&b speakers we use is excellent. This project shows IOSONO’s high potential for live applications.” After being audio-streamed to the venue, the orchestra sound is unfolding three-dimensionally for every listener. With the use of IOSONO’s 3D sound technology a precise direction-oriented reproduction of each instrument is possible. Plus, more than a dozen effect speakers are placed throughout the Opera Theatre to further enhance the room acoustics and produce unique spatial sound effects offstage.

IOSONO’s technology is based on the principles of wave field synthesis and allows for a very precise sound reproduction across the whole listening area. The heart of each system is IOSONO’s audio processor, which flexibly adapts the sound to different loudspeaker setups, independent of the venue and for every audience member. IOSONO guarantees a unique three dimensional listening experience, letting the audience of Sydney Opera House dive into the third dimension of sound.
