ILDrms, ITDrms, and DV based on the SIED for binaurally modulated wideband and narrowband stimuli from Evilsizer et al. (2002). The x axis shows the modulation depth of the binaural modulator. Four different symbols are used to represent the four kinds of modulations: Black circles for binaural AM, red crosses for diotic, black squares for binaural QFM, and red triangles for mixed modulation. Relations between SIED and ILD, ITD cues are illustrated: If ITD dominates the SIED cue, then the pairs of symbols connected or circled by blue lines should overlap; if ILD dominates the SIED cue, then the pairs of symbols connected or circled by the green lines should overlap.
