The research presented in this paper investigates height perception of audio signals that have been recorded with microphone arrays recently presented by Lee and Williams. A test method was established in which test signals were recorded from a set of different azimuth and elevation positions. Later, the recorded signals are played back with a 3D loudspeaker setup. In a listening test experienced listeners gave information about perceived elevation, azimuth, apparent source width and spaciousness of auditory events. Points of interest are the relationship between recorded and perceived angle as well as how source width and room impression is evaluated regarding to different recording elevations. The results show, that elevated sources can be reproduced under certain circumstances. The results differ for the microphone setups and for the signal types. However, the results of the listening test give hints how elevated sources are localized.
