3D Audio Effects for Multi-Channel Reproduction

Immersive audio is devoted to offering a new perceptual experience for the users and a lot more possibilities for sound designers. Going beyond the actual audio exhibition systems commonly used at home, in movie theaters and even in sound installations, the 3D audio technologies are designed to take full advantage of the use of space, but being independent of any particular speaker configuration or layout, to create a natural listening experience in which the user perceives sound coming from locations anywhere around him. This project is oriented to explore and experiment with the technology platform developed in the Audio Group of Barcelona Media Innovation Center to create audio effects that will serve as tools for music creation and performance from a 3D perspective. Four different case studies are presented as methodologies and research sources; using signal processing techniques, efficient real-time audio-oriented processing software, and spatialization algorithms to render 3D audio. A general framework is presented as a strategy to develop audio effects that are designed to be reproduced in three-dimensional audio exhibition systems
