Abstract:
This work is a treatise on three-dimensional sound recording. It explores the suit-
ability of spherical microphone arrays in music recording. A detailed discussion of
spatial audio theory culminates in a unified representation of sound fields using the
spherical harmonic transform. Diverse and alternative array architectures are sim-
ulated with regard to their performance. A mathematical model using a new error
measure is given and employed in the evaluation of different array layouts and their
possible imperfections. An implementation of the algorithms is shown and verified
in test recordings using an actual array construction. The obtained results lead to
an analysis and to possible improvements for the hardware and signal processing
chain.
