Abstract


A library for the use with Miller Puckettes open source computer music software Pure Data (PD) is presented. The library is downloadable for free and you can use it under the terms of GNU General Public License.
The theory that forms the basis of the proposed library is an improved Virtual Ambisonics Approach. Using this approach provides a computationally efficient implementation of virtual environments with
  • Multiple moving sound sources,
  • Room simulation,
  • Head tracking,
  • Time varying listener positions, and
  • Interchangeable HRIR settings
The proposed library provides a simple API (application programmers interface) to make it easy to use for scientific as well as for artistic projects.

Plone makes heavy use of CSS, which means it is accessible to any internet browser, but the design needs a standards-compliant browser to look like we intended it. Just so you know ;)
