During exhibit hours at ShowEast 2013 this week in Hollywood, Florida, QSC Audio Products, LLC, is demonstrating a proof of concept of an end-to-end solution for the playback of object-based immersive sound program material in their booth #709 on the trade show floor.
The demonstrations highlight the capability of the QSC Q-SYS audio signal processing and routing platform to render MDA (multi-dimensional audio) files in real-time.
MDA is an open platform, object-based audio format developed by DTS, Inc. that allows every element of a soundtrack to be mapped in 3D space, storing all of the spatial and behavioral information as metadata. For the demos, test program content files were created using a ProTools MDA plug-in at The Dub Stage, a prominent Hollywood, CA post-production facility. The audio files were combined into a DCP (digital cinema package), which will be played back through a Doremi server, then synched and rendered through the QSC Q-SYS Core processor.
Q-SYS is a complete platform for digital audio signal processing, control and management. The primary elements of a Q-SYS system are the Core, Q-SYS Designer software, the Q-LAN network, and peripherals. The Q-SYS Core is the brain of the system, performing all audio routing, processing, and control functions. Q-SYS Designer software provides the interface for system design, configuration, and control. Q-LAN is the IP-friendly network that connects the system into an integrated whole. A variety of hardware peripherals (such as I/O Frames, I/O cards, and touch screen controllers) provide fully customizable and completely-scalable functionality.
In addition to serving as the rendering engine, the Q-SYS Core also provides all necessary audio signal processing (such as equalization) and signal routing to the appropriate power amplifiers and loudspeakers.
“Q-SYS is an extremely powerful processing platform that can be the central processor for any type of immersive audio format,” says Barry Ferrell, Senior Vice President & Chief Strategy Officer for QSC. “Because of its scalable nature and the variety of hardware options, a Q-SYS system can handle as many channels or ‘objects’ as is required by the format. The result is a single processing platform that can support multiple audio formats with separate storable pre-sets for signal processing functions like equalization, level and routing.”
