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');
