demo_mckenzie2022 - Demo for the model of colouration between binaural signals

Description:

This is a demonstration of mckenzie2022, a model predicting the coloration between two binaural signals in terms of the perceptual binaural coloration (PBC) scores. The demonstration compares various binaural Ambisonic renderers with and without diffuse-field equalisation of the HRTFs as used in McKenzie et al. (2018). It also shows how to plot the PBC scores using plot_mckenzie2022.

PBC scores calculated based on signals from McKenzie et al. (2018) for various Ambisonic orders (OAs) and with and without diffuse-field equalization (DFE).

PBC dataset normalisation; marker colours get lighter with iterations (see Fig. 2 of McKenzie et al., 2022)

PBC scores calculated calculated from frequency-domain data
