Abstract
The equalization of loudspeaker frequency response is necessary to conduct many types of well-controlled auditory experiments. This article introduces a program that includes functions to measure a loudspeaker’s frequency response, design equalization filters, and apply the filters to a set of stimuli to be used in an auditory experiment. The filters can compensate for both magnitude and phase distortions introduced by the loudspeaker. A MATLAB script is included in the Appendix to illustrate the details of the equalization algorithm used in the program.
