Improving the Magnitude Responses of Digital Filters for Loudspeaker Equalization

There are numerous techniques that can approximate the frequency and phase response of an analog filter when converted into its digital counterpart. A new transform technique was shown to be comparable or superior to traditional transform techniques. The resulting filters were closer to the ideal analog version over the full frequency range. The approach was applied successfully to the kind of filters that would be used for loudspeaker equalization.
