This workshop focuses on the new LBAP algorithm and the supporting D4 Max library's collection of tools for real-time 3D audification, sonfication, and interactive performance in High Density Loudspeaker Array (HDLA) scenarios. It will cover theory and application of the said tools, including its unique features, including the Spatialization Mask, Motion Blur, Radius, and advanced shape painting and rendering. Participants will be given an hands-on opportunity to experiment with the software and learn how to create a scalable and transportable systems that can adapt to most speaker configurations.

Of particular focus will be learning ways to import and integrate multidimensional data and render it spatially in real-time. So far, LBAP and D4 have been successfully tested with configurations of up to 137 loudspeakers and up to 1,011 concurrent 24-bit 48KHz audio streams with sub 22ms latency. The workshop may be of particular interest due to its focus on 3D spatial auditory displays using HDLA. It will be the first public workshop on a newly developed technology and is being offered in addition to a paper submitted to the conference.

Given the focus on multichannel audio, aural components of the workshop will leverage existing audio infrastructure while also providing alternative visual tools for experiencing spatialized audio. While participation without obtaining the tools is possible and encouraged, for optimal experience participants should consider obtaining the software online at http://ico.bukvic.net/main/d4/ or sold on site—special pricing will be provided workshop participants. For additional info on the software and pricing, please contact the author. Considering the D4 library is specifically designed for the Max environment, participants who decide to obtain the D4 library will need a Max license and a laptop (Windows or Mac) with the up-to-date 64bit Java libraries installed.
