Title
Artifacts in the sound field of a moving sound source reconstructed from a microphone array recording
Abstract
We present an analysis of the sound field of a moving sound source reconstructed from recordings of a virtual dual-radius open-sphere microphone array. As a consequence of the discrete property of such microphone distributions artifacts arise, most notably spatial aliasing and spatial bandwidth limitation artifacts. We show that these artifacts are much more pronounced for moving sound sources than for static ones. We analyze the artifacts with a focus on a possible perceptual impairment when such recordings are used for audition purposes.
