We introduce a novel algorithm for the decomposition of a broadband soundfield into its component plane-waves. The algorithm, termed Sequential Direction Detection, decomposes the sound-field into L plane waves by recursively minimizing an objective function that determines the plane-wave directions…
The nonuniform fast Fourier transform comprises a set of algorithms which approximately interpolate the usual discrete Fourier transform in the time and/or frequency domain. A nonuniform fast Fourier transform based on the fast multipole method was previously developed but passed over in favor of ot…
Any acoustic sensor disturbs the spatial acoustic field to certain extent, and a recorded field is different from a field that would have existed if a sensor were absent. Recovery of the original (incident) field is a fundamental task in spatial audio. For some sensor geometries, the disturbance of…
