Representation of sound fields for audio recording and reproduction
At Acoustics 2012: 11ème Congrès Français d’Acoustique. Annual meeting of the Institute of Acoustics, France.
23 - 27 Apr 2012.
Spherical and circular microphone arrays and loudspeaker arrays are often used for the recording and reproduction
of a given sound field. A number of approaches and formats are available for the representation of the recorded
field, some of which are more popular among the audio engineering community (B-format, virtual microphones,
etc.) whilst other representations are widely used in the literature on mathematics (generalized Fourier series,
single layer potential, Herglotz wave function, etc.). In this paper, some of the properties of the various approaches
and some of their differences are discussed. The analysis includes the representation of near-field sources and the
choice of basis functions used for the representation.
