The plenacoustic function on the circle with application to HRTF interpolation
2005
IEEE Conference on Acoustics, Speech and Signal Processing
The sampling of the soundfield using circular microphone arrays is studied. We give a new representation of the soundfield sampled on such an array using the two-dimensional Fourier transform. We then show how we can reconstruct the soundfield at all possible po- sitions on the array from a finite number of measurements. We give the necessary azimuthal angular sampling frequency necessary to reconstruct the data up to some temporal frequency. This new tech- nique is applied to interpolate Head Related Transfer Functions (HRTFs) where we also derive an angular sampling theorem.
