Digital equalisation of room acoustics based on inverse filtering of measured response functions, introduces a number of theoretical and practical challenges. To overcome such problems, inverse filtering based on modified measured responses is proposed, derived via their complex Transfer Function smoothing, so that the processed responses are more perceptually compliant, of lower order and less position-sensitive than the original functions. Aim of this study is to evaluate via objective and subjective tests conducted for different-sized rooms and real-time reproduction, the use of such smoothed room responses for the derivation of appropriate room equalisation filters, which can improve the perceived and measured quality of audio reproduction in any reverberant environment.
