DEMO_BARUMERLI2021 - Demo for full sphere localization model from Barumerli et al. (2021)

Description

demo_barumerli2021(flag) demonstrates how to compute and visualize the baseline prediction (localizing broadband sounds with own ears) on the full sphere using the localization model from Barumerli et al. (2021).

Baseline prediction

This demo computes the baseline prediction (localizing broadband sounds with own ears) for an exemplary listener (NH12).

Averaged polar and lateral accuracy

This code produces the following output:
