Improved microphone array configurations for auralization of sound fields by Wave Field Synthesis.

In order to correctly reproduce ( “auralize” ) the acoustic wave field in a hall through a wave-field synthesis (WFS) system, impulse responses are nowadays measured along arrays of microphone positions. Three array configurations are considered ‐ linear, cross, and circular. The linear and cross array configurations both have strong limitations, most of which can be avoided by using circular arrays. Auralization techniques are explained for all types of arrays. For the circular array configuration the connection between circular holophony, highorder incoming and outgoing ambisonics, and plane-wave decomposition for a sound field will be established and used as a tool for auralization.
