A variety of aeroacoustic problems involve small-amplitude linear wave propagation. Highorder schemes have the accuracy and the low dispersion and dissipation wave propagation properties that are required to model linear acoustic waves with minimal spatial resolution. This review presents a selection of high-order finite difference time-explicit schemes for aeroacoustic applications. A scheme selection method based on the computational cost for a given accuracy level is proposed.
