Distance Coding in 3D Sound Fields

摘要

This investigation proposes a possibility to synthesise 3D sound fields over loudspeakers taking distance coding into account. The system can be divided into two parts combining the benefits both using the Wave Field Synthesis (WFS) and the Ambisonic approach. In order to code the virtual source distances the driving functions using a derivative of the WFS approach are primarily calculated. In the second step the apparent solid angle of the sources are coded using the extended Ambisonic approach.
