AB  - Extensive research has investigated the relative influence of interaural level and time differences (ILDs and ITDs) on the perceived position of aural stimuli. Historically, these cues have been compared using trading methods with stimuli presented over headphones. For the purpose of virtual audio applications using multichannel techniques, it is important to establish whether interaural cues are exploited similarly in such listening conditions. In this work, trading experiments were carried out both with stimuli presented over headphones and using a novel two-listener crosstalk cancellation array. Listener responses revealed similar trading behaviour in the crosstalk cancellation case when compared to the headphones case. At the lowest frequency tested, the measured trading behaviour is considered less reliable due to inaccuracies in reproduction of the target stimuli. With this exception, this work demonstrates that the general trends observed in historical ILD/ITD trading experiments also apply to stimuli presented using crosstalk cancellation, namely increased sensitivity to ILD and decreased sensitivity to ITD with increasing frequency.
