Vienna Power House

Vienna Power House – Harnessing the Power of Your GPU!

 Boost your computer’s performance at the touch of a button! Vienna Power House is a groundbreaking add-on for Vienna MIR Pro 3D that offloads convolution processes to the graphics card in order to reduce the load on the CPzU. Utilizing GPU Audio’s patented technology, this powerful acceleration component, available for Vienna MIR Pro 3D and the Vienna Synchron Player, uses the vast processing capabilities of the more adaptable and streamlined GPU to free up the CPU for other tasks. 

Vienna Power House works best in connection with Vienna MIR Pro 3D and Vienna MIR Pro 3D (24). MIR’s core engine relies on convolution for placement and reverberation. This mathematical process taxes the CPU in a linear way. More audio sources, more output channels (from stereo to immersive formats), and long reverb tails may result in hundreds, even thousands of convolutions. An orchestra consisting of 80 stereo sources, mixed in 7.0.4 for Dolby Atmos, will create a maximum of 1,760 positional impulse responses and consequently the same number of convolutions (80 x 2 x 11), calculated in real-time at a preferably low latency. By lowering the CPU load by up to 50% or more, depending on your system, Vienna Power House provides you with significantly increased raw computation power at the click of the “GPU Power” button.


Vienna Power House also works in connection with the Vienna Synchron Player. Naturally, as opposed to Vienna MIR Pro 3D’s vast amount of convolutions, the number of convolutions with the SYNCHRON-ized Libraries is usually limited to two for stereo samples and up to eight for SYNCHRON-ized Dimension Strings and Brass. (Synchron Libraries were recorded at Synchron Stage Vienna so they don’t use any convolution reverb.) The potential for outsourcing processes to the CPU is therefore relatively limited with the Vienna Synchron Player.
