Methods of loudspeaker response equalization using digital filters are compared. In addition to generally known methods and techniques, a recently introduced new principle, based on warped filters, is described. Different equalization methods are compared from the points of view of equalization error both objectively and subjectively, computational efficiency, as well as robustness and precision requirements of each method. The study is limited to the linear (magnitude and phase) equalization of loudspeaker free-field responses.
