Sound enhancing algorithms are becoming more and more common in our media devices (such as A/V receivers, computers and cellphones) and are often used as a selling argument. In this study, Virtual Home Theatre algorithms for headphones (VHT algorithms) are subjectively evaluated and compared against a stereo down mix. The algorithms are also compared against each other.A listening test has been conducted when listeners were asked to evaluate their preference when comparing algorithms in pairs. The result of the experiment will show subject’s ratings that might give an answer to the question if the VHT algorithms are any different or preferred to each other. According to the result, no algorithm is significantly preferred against the other algorithms tested in this research. However one algorithm turned out to be significantly non-preferred.
