Room equalization has the potential to create improved audio display for homes, cars, and professional applications. In this paper, the signal is inverse filtered using an inverse filter computed by using newly introduced regularized optimal multi-point frequency-warped linear prediction coefficients. We present experimental results which show that the proposed room equalization algorithm improves equalization on the equalizable parts, thus enlarging the region of perceptually effective equalization.
