AB  - A system to improve the perception of elevated sources is presented. This method relies on “equalizing filters,” a technique that aims to compensate for unintended changes in the magnitude spectrum produced by the placement of loudspeakers with respect to the desired location. In the proposed method, when sources are on the horizon, a maximum of two loudspeakers are used for reproduction. Otherwise, the horizon spatialization is mixed with one that uses side loudspeakers grouped by lateral direction. Results from a subjective experiment suggest that the proposed method is capable of producing elevated images, but the perceived elevation range is somewhat compressed.
