A criteria for equalizing the output of binaural stereo rendering networks in order to preserve the sound quality of the headphone is described and evaluated. This equalization process aims to flatten the magnitude at the output of the binaural network for stereo reproduction. The equalization criteria is evaluated using listening tests where different binaural filter designs were used. The results showed that flattening the output of the binaural stereo network does not degrades the timbre quality of the headphone as much as the lack of accurate binaural information degrades the spatial quality of the reproduction. Furthermore, post equalization of measured binaural responses was found to reproduce better the expectations of the test participants for virtual stereo reproduction over loudspeakers.
