Plots of interaural cues of listening experiment conditions (exact vs. experiment approximation)

The plots show interaural cohehrence (IC) and interaural level difference (ILD) for a subset of experiment conditions presented in the JASA-EL publication 'Surrounding line sources optimally reproduce diffuse envelopment at off-center listening positions'. The experiment compared on-center with off-center listening (0.5 times radius). Off-center listening was simulated by remapped loudspeaker signals in a 24-channel loudspeaker setup. The nearest available loudspeaker was chosen for a direction shift, and the approximated angles (approx.) lead to negligible deviations in interaural cues compared to the interaural cues of an actually shifted listener (exact). Curves result from IC and ILD computations in 320 gammatone frequency bands, using a KU100 HRTF database.
