Sound diffusion, spatialization and localization is an ongoing passion for the LSU EMDM program.  Using a loudspeaker orchestra or Massively Multi-channel Audio System, we perform pieces by diffusing sound across the array, taking advantage of the room acoustics, size and shape of the loudspeakers, and directionality of the speakers.  Through this process of diffusion, we are able to enhance recorded and live music and articulate its key elements much the way a pianist would interpret a piece of piano music.

We are interested not only in composing works for massively multichannel audio, but also developing control systems to map, project or otherwise manage performance across these systems.  Below are the resources we have available for research in the area.

ICAST

To assist us in the process of diffusion, we have created a (portable!) 27-channel loudspeaker array known as the Immersive Computer-controlled Audio Sound Theatre or ICAST. This sound system enables musicians to diffuse sound across a large number of discreet speakers using intuitive controls and technologies. The system uses a client/server software created at LSU that links the mixing station and the audio servers with various traditional and experimental interface controls such as haptic interfaces (such as the Firefader), video tracking, Leap Motion, and Mobile Devices.
