    Aegis Audio Engine: Integrating a Real-Time Analog Signal Processing, Pattern Recognition, and a Procedural Soundtrack in a Live Twelve-Perfomer Spectacle With Crowd Participation
    Bukvic, Ivica Ico; Matthews, Michael (Georgia Institute of Technology, 2015-07)
    In the following paper we present Aegis: a procedural networked soundtrack engine driven by real-time analog signal analysis and pattern recognition. Aegis was originally conceived as part of Drummer Game, a game-performancespectacle hybrid research project focusing on the depiction of a battle portrayed using terracotta soldiers. In it, each of the twelve cohorts—divided into two armies of six—are led by a drummer-performer who issues commands by accurately drumming precomposed rhythmic patterns on an original Chinese war drum. The ensuing spectacle is envisioned to also accommodate large audience participation whose input determines the morale of the two armies. An analog signal analyzer utilizes efficient pattern recognition to decipher the desired action and feed it both into the game and the soundtrack engine. The soundtrack engine then uses this action, as well as messages from the gaming simulation, to determine the most appropriate soundtrack parameters while ensuring minimal repetition and seamless transitions between various clips that account for tempo, meter, and key changes. The ensuing simulation offers a comprehensive system for pattern-driven input, holistic situation assessment, and a soundtrack engine that aims to generate a seamless musical experience without having to resort to cross-fades and other simplistic transitions that tend to disrupt a soundtrack’s continuity.

    The Making of Leork: The Virginia Tech Linux Laptop Orchestra
    Bukvic, Ivica Ico; Matthews, Michael; Renfro, Maya; Wood, Andrew (2009)
    This poster describes the making of Leork, the Virginia Tech Linux Laptop Orchestra. The challenge of the project was to assemble a laptop orchestra using open source software, create self-constructed speakers, and obtain netbooks for a minimal cost. The project goals were to design and build a website, build hemispherical speakers, and construct software patches in Pure Data. At the project's conclusion, 16 hemispherical speakers were built, a website was developed and made available at 12ork.music.vt.edu, and all software patches were completed.
