%   Usage: [] = exp_klingel2022(flag) 
%
%   EXP_KLINGEL2022(flag) reproduces figures of the study from  
%   Klingel & Laback (2022).
%
%
%   The following flags can be specified
%
%     'fig3'    Reproduce Fig.3:
%               Pretest ILD weights for each frequency band, averaged 
%               across azimuths. Blue circles show the results of 
%               experiment 1, red triangles of experiment 2. ILD weights 
%               gradually increase for single-band conditions from low 
%               (794-1260 Hz), to mid-low (1414-1782 Hz), to mid-high 
%               (2245-2828 Hz), to high (3564-4490 Hz). The multiband 
%               condition shows ILD weights similar to the mid-low band.
%
%     'fig4'    Reproduce Fig.4:
%               ILD weights as a function of azimuth for each frequency 
%               band (columns) and group (rows; top row shows ITD groups,
%               bottom row shows ILD groups). ILD weights gradually 
%               increase from low- to high-frequency stimuli and on average
%               are lower for lateral azimuths. Significant weight changes
%               from pre- to posttest were observed for the ILD group in 
%               experiment 1 for the high-frequency band as well as in 
%               experiment 2 for the mid-high-frequency band. Additionally, 
%               a significant weight change from pre- to posttest was 
%               observed for the ITD group in experiment 1 for the mid-low-
%               frequency band at 9 deg azimuth as well as in experiment 2 at 
%               39 deg azimuth.
