The Royal Danish Academy of Music in Copenhagen has chosen Ambisonic immersive sound with 48 channels using 44 speakers and four subwoofers.
The Academy is using DAD Audio’s AX32 digital format converter as the audio routing centerpiece. The system features an AD/DA converter and monitor controller and changes between workflows in seconds.
With all I/O card and options installed, the AX32 can control a 1,500 x 1,500 matrix of audio channels. Eight I/O cards and two I/O modules can be installed. Control is managed via the DADman control software.
“Ideally, the speakers should form a hemisphere and ideally place the listener right in the middle,” said Jesper Andersen, associate professor and head of Tonmeister Studies at the Royal Danish Academy of Music. “We used a measurement microphone and determined the distance to the speaker that was the farthest away, and then we added delay to the rest in order to emulate a perfect circle in each speaker plane."
Using the AX32 with the SPQ card brought the Academy closer to the perfect hemisphere, delivering within a one-millisecond margin.
“In contemporary classical music that often includes one or more electronic elements, composers have experimented with placing speakers behind the audience or on the sides as far back as the 1950’s, 60’s and 70’s,” Andersen said. “In fact, there are examples in music history, dating back as far as the 17th century, about notes in the sheets that for example would place a musician behind the audience.”
The immersive Ambisonics hall at The Royal Danish Academy of Music was officially opened last September.
