Abstract
Subjective listening tests of the spatial cues interaural time difference (ITD), interaural level difference (ILD), and interaural coherence (IC) from 20 Hz to 15500 Hz are presented. To obtain the just noticeable difference (JND) of the cues, which is an indication of spatial hearing significance, we expand raw test data by the bootstrap method. The tests show the spatial cues have frequency dependence at different extent, implying a frequency-aware cue selection scheme is more economic in spatial stereo coding.
