In order to correctly reproduce the acoustic wave field in a hall over a large listening area through a Wave Field Synthesis reproduction system, impulse responses are nowadays measured along arrays of microphone positions. These measurements could be used directly for reproduction if the positions of the microphones in the hall correspond to the positions of the loudspeakers in the reproduction array (holophony). However, this approach is not very flexible and the amount of data and real-time processing required is extremely large. Therefore a relatively small circular microphone array is used instead and the measured data are spatially and temporarily parameterized to obtain more playback flexibility and to reduce the amount of data and real-time processing without sacrificing perceptual quality and listening area size. In this paper these parameterization techniques are discussed and applied to circular array measurements done in the Amsterdam Concertgebouw. The main application of all this is future high quality audio with realistic room acoustic reproduction over a large listening area.
