%EXP_BAUMGARTNER2014 Results from Baumgartner et al. (2014)
% Usage: data = exp_baumgartner2014(flag)
%
% EXP_BAUMGARTNER2014(flag) reproduces figures of the study from
% Baumgartner et al. (2014).
%
%
% The following flags can be specified
%
% 'fig2' Reproduce Fig.2:
% Binaural weighting function best fitting results from
% Morimoto (2001) labeled as [1] and Macpherson and Sabin (2007)
% labeled as [2] in a least squared error sense.
%
% 'fig3' Reproduce Fig.3:
% Prediction examples. Actual responses and response predictions
% for three exemplary listeners when listening to median-plane
% targets in the baseline condition.
% Actual response angles are shown as open circles.
% Probabilistic response predictions are encoded by brightness
% according to the color bar to the right. Actual (A:) and
% predicted (P:) quadrant error rates (QE) and local polar
% RMS errors (PE) are listed above each panel.
%
% 'fig4' Reproduce Fig.4:
% Model parametrization. Partial and joint prediction residues
% as functions of the degree of selectivity and the motoric
% response scatter. Residuum functions are normalized to the
% minimum residuum obtained for the optimal parameter value.
%
% 'fig5' Reproduce Fig.5:
% Effect of band limitation and spectral warping. Actual
% responses and response predictions for listener NH12 when
% listening to broadband (BB), low-pass filtered (LP), or
% spectrally warped (W) DTFs of the median plane. Data were
% pooled within pm15^circ of lateral angle.
% All other conventions are as in Fig.3.
%
% 'fig6' Reproduce Fig.6:
% Effect of band limitation and spectral warping.
% Listeners were tested with broadband (BB), low-pass
% filtered (LP), and spectrally warped (W) DTFs.
% Actual: experimental results from Majdak et al. (2013).
% Part.: Model predictions for the actual eight participants
% based on the actually tested target positions. Pool: Model
% predictions for our listener pool based on all possible
% target positions. Symbols and whiskers show median values
% and inter-quartile ranges, respectively. Symbols were
% horizontally shifted to avoid overlaps. Dotted horizontal
% lines represent chance rate. Correlation coefficients, r,
% and prediction residues, e, specify the correspondence
% between actual and predicted listener-specific performances.
%
% 'fig7' Reproduce Fig.7:
% Effect of spectral resolution in terms of varying the number
% of spectral channels of a channel vocoder. Actual responses
% and response predictions for exemplary listener NH12.
% Results for 24, 9, and 3 channels are shown. All other
% conventions are as in Fig.3.
%
% 'fig8' Reproduce Fig.8:
% Effect of spectral resolution in terms of varying the number
% of spectral channels of a channel vocoder. Actual experimental
% results are from Goupell et al. (2010). Stimulation with broadband
% click trains (CL) represents an unlimited number of channels.
% All other conventions are as in Fig.6.
%
% 'fig9' Reproduce Fig.9:
% Effect of non-individualized HRTFs in terms of untrained
% localization with others' instead of own ears. Statistics
% summaries with open symbols represent actual experimental
% results replotted from Fig.,13 of Middlebrooks (1999),
% statistics with filled symbols represent predicted results.
% Horizontal lines represent 25th, 50th, and 75th percentiles,
% the whiskers represent 5th and 95th percentiles, and crosses
% represent minima and maxima. Circles and squares denote mean values.
%
% 'fig10' Reproduce Fig.10:
% Effect of spectral ripples. Actual experimental results (circles)
% are from Macpherson and Middlebrooks (2003). Predicted results (filled circles)
% were modeled for our listener pool (squares). Either the ripple
% depth of 40,dB (top) or the ripple density of one ripple/octave
% (bottom) was kept constant. Ordinates show the listener-specific
% difference in error rate between a test and the baseline condition.
% Baseline performances are shown in the bottom right panel.
% Symbols and whiskers show median values and inter-quartile ranges,
% respectively. Symbols were horizontally shifted to avoid overlaps.
% Diamonds with dashed lines show predictions (P) of the model
% without positive spectral gradient extraction (PSGE).
%
% 'fig11' Reproduce Fig.11:
% Effect of high-frequency attenuation in speech localization.
% Actual experimental results are from Best et al. (2005).
% Absolute polar angle errors (top) and QE (bottom) were averaged
% across listeners. Circles and squares show actual and predicted
% results, respectively. Diamonds with dashed lines show predictions
% of the model without positive spectral gradient extraction.
%
% 'fig12' Reproduce Fig.12:
% Listener-specific likelihood statistics used to evaluate
% target-specific predictions for baseline condition. Bars
% show actual likelihoods, dots show mean expected likelihoods,
% and whiskers show tolerance intervals with 99% confidence
% level of expected likelihoods.
%
% 'fig13' Reproduce Fig.13:
% Exemplary baseline predictions. Same as Fig.3 but for listeners
% where actual likelihoods were outside the tolerance intervals.
%
% 'fig14' Reproduce Fig.14:
% Baseline performance as a function of the magnitude of the
% lateral response angle. Symbols and whiskers show median
% values and inter-quartile ranges, respectively. Open symbols
% represent actual and closed symbols predicted results. Symbols
% were horizontally shifted to avoid overlaps. Triangles with
% dashed lines show predictions (P) of the model without the
% sensomotoric mapping (SMM) stage.
%
% 'tab1' Reproduce Tab.1:
% Listener-specific sensitivity calibrated on the basis of N
% baseline targets in proximity of the median plane (+-30deg).
% Listeners are labeled as NHl. Actual and predicted quadrant
% errors (QE) and local polar RMS errors (PE) are shown pairwise
% (Actual | Predicted).
%
% 'tab2' Reproduce Tab.2:
% The effects of model configurations on the prediction residues.
% PSGE: model with or without positive spectral gradient extraction.
% MBA: model with or without manual bandwidth adjustment to the
% stimulus bandwidth. Prediction residues between actual and
% predicted PE and QE are listed for acute performance with
% the broadband (BB), low-passed (LP) and warping (W) conditions
% of the experiments from Majdak et al. (2013).
%
% 'tab3' Reproduce Tab.3:
% Performance predictions for binaural, ipsilateral, and
% contralateral listening conditions. The binaural weighting
% coefficient was varied in order to represent the three
% conditions: binaural: Phi = 13^circ;
% ipsilateral: Phi rightarrow +0^circ;
% contralateral: Phi rightarrow -0^circ.
% Prediction residues and correlation coefficients between
% actual and predicted results are shown together with predicted
% average performances.
%
% 'fig5_baumgartner2015aro' Reproduce Fig.5 of Baumgartner et al. (2015):
% Effect of background noise on reliability of contralateral
% cues for various lateral eccentricities. Top row:
% Across-listener averages of performance measures for
% contralateral ear. Bottom row: Contralateral re ipsilateral
% averages of performance measures.
%
% 'fig2_baumgartner2015jaes' Reproduce Fig.2 of Baumgartner and Majdak (2015):
% Example showing the spectral discrepancies obtained by VBAP.
% The targeted spectrum is the HRTF for 20 deg polar angle.
% The spectrum obtained by VBAP is the superposition of two
% HRTFs from directions 40 deg polar angle apart of each
% other with the tar- geted source direction centered in between.
%
% 'fig4_baumgartner2015jaes' Reproduce Fig.4 of Baumgartner and Majdak (2015):
% Response predictions to sounds created by VBAP with two
% loudspeakers in the median plane positioned at polar
% angles of -15 and 30 deg, respectively. Predictions for
% two exemplary listeners and pooled across all listeners.
% Each column of a panel shows the predicted PMV of
% polar-angle responses to a certain sound. Note the
% inter-individual differences and the generally small
% probabilities at response angles not occupied by the loudspeakers.
%
% 'fig5_baumgartner2015jaes' Reproduce Fig.5 of Baumgartner and Majdak (2015):
% Listener-specific increases in polar error as a function of
% the panning angle. Increase in polar error defined as
% the difference between the polar error obtained by the
% VBAP source and the polar error obtained by the real
% source at the corresponding panning angle. Same loudspeaker
% arrangement as for Fig. 4. Note the large inter-individual
% differences and the increase in polar error being largest
% at panning angles centered between the loudspeakers, i.e.,
% at panning ratios around R = 0 dB.
%
% 'fig6_baumgartner2015jaes' Reproduce Fig.6 of Baumgartner and Majdak (2015):
% Panning angles for the loudspeaker arrangement of Fig. 4
% judged best for reference sources at polar angles of
% 0 or 15 deg in the median plane. Comparison between
% experimental results from [2] and simulated results
% based on various response strategies: PM, CM, and both
% mixed. Dotted horizontal line: polar angle of the reference
% source. Hor- izontal line within box: median;
% box: inter-quartile range (IQR);
% whisker: within quartile +-1.5 IQR;
% star: outlier.
% Note that the simulations predicted a bias similar to
% the results from Pulkki (2001) for the reference source at 0 deg.
%
% 'tab1_baumgartner2015jaes' Reproduce Tab.1 of Baumgartner and Majdak (2015):
% Means and standard deviations of responded panning angles for the
% two reference sources (Ref.) together with corresponding GOFs
% evaluated for the actual results from Pulkki (2001) and
% predicted results based on various response strategies.
% Note the relatively large GOFs for the simulations based on
% mixed response strategies indicating a good correspondence
% between actual and predicted results.
%
% 'fig7_baumgartner2015jaes' Reproduce Fig.7 of Baumgartner and Majdak (2015):
% Increase in polar error (defined as in Fig. 5) as a function
% of loudspeaker span in the median plane with panning ratio
% R = 0 dB. Black line with gray area indicates mean
% +-1 standard deviation across listeners. Note that the
% increase in polar error monotonically increases with
% loudspeaker span.
%
% 'fig8_baumgartner2015jaes' Reproduce Fig.8 of Baumgartner and Majdak (2015):
% Effect of loudspeaker span in the median plane on coefficient
% of determination, r^2, for virtual source directions
% created by VBAP. Separate analysis for frontal, rear,
% and overall (frontal and rear) targets. Data pooled
% across listeners. Note the correspondence with the
% results obtained by Bremen et al. (2010).
%
% 'tab3_baumgartner2015jaes' Reproduce Tab.3 of Baumgartner and Majdak (2015):
% Predicted across-listener average of increase in polar
% errors as referred to a reference system containing
% loudspeakers at all considered directions. Distinction
% between mean and maximum degradation across directions.
% N: Number of loudspeakers. Ele.: Elevation of second layer.
% Notice that this elevation has a larger effect on mean
% and maximum degradation than N.
%
% 'fig9_baumgartner2015jaes' Reproduce Fig.9 of Baumgartner and Majdak (2015):
% Predicted polar error as a function of the lateral and
% polar angle of a virtual source created by VBAP in
% various multichannel systems. Open circles indicate
% loudspeaker directions. Reference shows polar error
% predicted for a real source placed at the virtual
% source directions investigated for systems A, ..., F.
%
% Further, cache flags (see amtcache) and plot flags can be specified:
%
% 'plot' Plot the output of the experiment. This is the default.
%
% 'noplot' Don't plot, only return data.
