[3] This plan was considered in the construction of the facility: In order to shield noise and vibrations from the outside world, the hall was isolated from the rest of the building by a custom foundation and insulated against air traffic by an elaborate roof structure.
A remnant of the building's designated use is the preserved "Lenkwil" cinema organ with three manuals that features not only various instrumental timbres but also sound effects such as rolling thunder, car horns, clopping horses, twittering birds and ocean waves.
Eminent classical artists such as Karl Böhm, Herbert von Karajan, Yehudi Menuhin, Sviatoslav Richter and Mstislav Rostropovich discovered the exceptional acoustic properties and used the "Synchronhalle" for many legendary recordings.
Subsequently, films such as Der Bockerer II - Österreich ist frei (1996), Comedian Harmonists (1997) and Die Klavierspielerin (2001) were shot on the Rosenhügel.
[8] The hall was purchased by the Vienna Symphonic Library in 2013 and developed into a globally unique music production facility in collaboration with the renowned Walters-Storyk Design Group and architects Schneider+Schumacher.
[17] It combines a scoring stage with several studios, isolation booths and office space used by clients and Vienna Symphonic Library's software and sample development business.
Stage A, the large main hall, accommodates orchestras of up to 130 musicians and is built as a room-in-room construction, with an up to 10-foot gap between walls, ensuring entire sonic isolation from outside noise.
[14] The facility offers the ability to route any signal source to any room of the building, including offices, without any latency or loss of audio quality.
[22][23] The Bösendorfer CEUS technology[24] and the Yamaha Disklavier reproducing system incorporate computer controlled mechanisms to record performances and accurately play them back on the acoustic instrument.
[26] The in-house "Synchron Stage Orchestra" is not a fixed ensemble but draws on a large pool of musicians from Vienna and the surrounding area.
They play in all the major orchestras in Vienna and have been selected according to strict criteria to meet the demands of modern media music productions.
[28][29] Recent notable projects include the film scores for The Meg (2018), Ad Astra (2019), Klaus (2019), as well as Promising Young Woman (2020) and Over the Moon (2020).
