Comparison of Loudspeaker Equalization Methods Based on DSP Techniques

摘要

Methods of loudspoaker 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 errors both objectively and subJectivety, computational efficiency, as well as robustness and precision requirements of each method. The study is limited to the linear (magnitude and phase) equalization of loudspoaker free-field responses.
