EXP_STEIDLE2019 - Compares various ITD calculation methods

Usage:

exp_steidle2019(flag)

Description:

The following flags can be chosen:

'clean' clean data
'noisy' noisy data
'stim' to create the data which was used
'figure' to create the plots shown in the paper (fig1,...`fig9`)
'lowpass' (optional) Decide if lowpass shall be applied. lp for lowpass (default), bb for broadband
'threshlvl' (optional) Set threshold level for 'Threshold mode in dB. Default is -10 dB.

Requirements:

  1. SOFA API from http://sourceforge.net/projects/sofacoustics for Matlab (in e.g. thirdparty/SOFA)

Examples:

To display results for Fig.1 use

exp_steidle2019('fig1');

This code produces the following output:

exp_steidle2019_1_1.png

To display results for Fig.2 use

exp_steidle2019('fig2');

This code produces the following output:

To recalculate the data sets use i.e.

exp_steidle2019('clean','lp');
