  The sampling of sound fields involves the measurement of spatially dependent
room impulse responses, where the Nyquist-Shannon sampling theorem applies in
both the temporal and spatial domain. Therefore, sampling inside a volume of
interest requires a huge number of sampling points in space, which comes along
with further difficulties such as exact microphone positioning and calibration
of multiple microphones. In this paper, we present a method for measuring sound
fields using moving microphones whose trajectories are known to the algorithm.
At that, the number of microphones is customizable by trading measurement
effort against sampling time. Through spatial interpolation of the dynamic
measurements, a system of linear equations is set up which allows for the
reconstruction of the entire sound field inside the volume of interest.
