Inverse filtering methods commonly use amplitude regularization as a technique to limit the amount of work done by the inverse filter. The amount of regularization needed must be carefully selected so that the audio quality is not degraded. This paper introduces a method of using the magnitude of the regularization to design a target/desired response in which the phase response can be arbitrarily chosen. By choosing a minimum-phase response, one can reduce any pre-response in the corrected signal that is introduced by the regularization. Objective measures, such as PEAQ and subjective tests conducted in accordance to the MUSHRA method are used to evaluate the subjective performance of this new approach of designing a target response.
