This thesis discusses a field-related recording technique based on microphone arrays and orthogonal sound field decomposition that delivers a suitable description for dynamic binaural reproduction. Using microphone arrays paired with orthogonal sound field decomposition appears to be a particularly promising approach for field-related dynamic binaural recording. It is based on an elegant, closed-form mathematical solution and allows accounting for head-tracking in all rotational degrees-of-freedom during the playback of a recorded auditory scene. The method inherently comprises individualization capabilities by employing individual head-related transfer functions (HRTFs) and allows for point-to-multipoint distribution.
