Interactive real-time spatialization of audio over large immersive speaker arrays poses significant interface and control challenges for live performers. Fluidly moving and mixing numerous sound objects over unique speaker configurations requires specifically designed software interfaces and systems. Currently available software solutions either impose configuration limitations, require extreme degrees of expertise, or extensive configuration time to use. A new system design, focusing on simplicity, ease of use, and live interactive spatialization is described. Automation of array calibration and tuning is included to facilitate rapid deployment and configuration. Comparisons with other solutions show favorability in terms of complexity, depth of control, and required features.
