A Discussion on the Application and Merits of Employing IIR Filter Structures to the Task of Acoustic Equalization
This paper presents two digital equalization techniques, one based on an FIR structure and the other on a hybrid FIR/IIR structure. Discussion is given on the forms each equalization approximation takes and, consequently, the beneficial attributes apropos audio equalization. A practical comparison of the two techniques is given which shows potential gains may be achieved using the hybrid FIR/IIR filter type.
