DATA_BAUMGARTNER2013 - Data from Baumgartner et al. (2013)
Program code:
function data = data_baumgartner2013(varargin)
%DATA_BAUMGARTNER2013 Data from Baumgartner et al. (2013)
% Usage: data = data_baumgartner2013(flag)
%
% DATA_BAUMGARTNER2013(flag) returns data of the table or
% the pool of listener-specific models from Baumgartner et al. (2013)
% describing a model for sound localization in sagittal planes (SPs)
% on the basis of listener-specific directional transfer functions (DTFs).
%
% The flag may be one of:
%
% 'tab1' Calibration data for listener pool listed in Table 1. The
% output contains the following fields: id, u, goupell10 and
% walder10*
%
% 'pool' DTFs and calibration data of the pool. The output contains the
% following fields: id, u, goupell10, walder10, fs*
% and Obj.
%
% 'ari' OBSOLETE. DTFs and calibration data of the pool. The output contains the
% following fields: id, u, goupell10, walder10, dtfs,
% fs and pos.
%
% The fields in the output contains the following information
%
% .id listener ID
%
% .u listener-specific uncertainty
%
% .goupell10 boolean flag indicating whether listener
% participated in Goupell et al. (2010)
%
% .walder10 boolean flag indicating whether listener
% participated in Walder (2010)
%
% .dtfs OBSOLETE. matrix containing DTFs.
% Dimensions: time, position, channel
% (more details see doc: HRTF format)
%
% .fs sampling rate of impulse responses
%
% .pos OBSOLETE. source-position matrix referring to
% 2nd dimension of hM and formated acc.
% to meta.pos (ARI format).
% 6th col: lateral angle
% 7th col: polar angle
%
% .Obj DTF data in SOFA Format
%
% Requirements:
% -------------
%
% 1) SOFA API from http://sourceforge.net/projects/sofacoustics for Matlab (in e.g. thirdparty/SOFA)
%
% 2) Data in hrtf/baumgartner2013
%
% Examples:
% ---------
%
% To get calibration data of pool of listener-specific models, use:
%
% data_baumgartner2013('tab1');
%
% To get all listener-specific data of the pool, use:
%
% data_baumgartner2013('pool');
