The Grosses Festpielhaus is a significant venue of the Salzburg Festival, one of the world’s most eminent festivals of music and drama. It was built in the 1950s on the site of the former archiepiscopal princely stables according to plans of Austrian architect Clemens Holzmeister, with suggestions on the building’s design from famed conductor Herbert von Karajan. MIR 3D RoomPack 7 features not only the fantastic acoustics of its main hall, but also the nearby Karl Böhm Hall, which is set into the rock face of Salzburg’s Mönchsberg.

The auditorium of Grosses Festspielhaus with 2,158 seats has an almost square floor plan with a side length of about 35 meters (115 ft.). With a regular front width of 22 meters (72 ft.) and a total width of 100 meters (328 ft.) including side stages, this stage is one of the widest in the world. The reflecting surfaces near the stage are arranged in a funnel-like fashion, resulting in an optimized acoustic “coupling” of the stage house to the hall. Orchestras sound elegant, wide and warm, engulfing the listener in a very natural and balanced way, with instruments still clearly locatable.
RoomPack 7 recreates this hall using an unprecedented amount of 6,400 impulse responses. They were captured with four Ambisonics microphones, alternatively placed in a height of approx. 2 and 4 meters above the ground for a true 3D rendition with spaced layers, and can be used in pairs: front and front elevated, back and back elevated. In addition to the large stage, virtual instruments or any audio signal can be placed on the wings of the stage and even behind the wooden lamellas on each side for creating distant voices.
This RoomPack contains room responses with augmented directional resolution, improving their spatial mapping in direction and depth. Our first-order measurements were augmented to third-order Ambisonics by Franz Zotter, Matthias Frank and Elias Hoffbauer (University of Music and Performing Arts in Graz, Institute of Electronic Music and Acoustics) in 2022.
