Ambisonic Spatialization for Networked Music Performance
MetadataShow full item record
In spite of recent widespread interest in network technologies for real-time musical collaboration between distant locations, there has been little focus on spatial audio in such applications. We discuss the potential for dynamic spatialization in the context of network music collaboration, in particular through the use of Higher Order Ambisonics. We describe a platform for real-time encoding, streaming and decoding of spatial audio using Ambisonics, and provide details of two case studies of creative applications built on top of this platform. We demonstrate that Higher Order Ambisonics is a viable and effective means for real-time, simultaneous spatialization in multiple locations, and that it enables a range of creative uses that explore the nature of space, distance and location in networked performance.
