DATA_BAUMGARTNER2013 - Data from Baumgartner et al. (2013)
Usage
data = data_baumgartner2013(flag)
Description
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 |
| 'ari' | DTFs and calibration data of the pool. The output contains the following fields: id, u, goupell10, walder10, dtfs, fs and pos |
| 'pool' | DTFs and calibration data of the pool. The output contains the following fields: id, u, goupell10, walder10, fs and Obj. |
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 | matrix containing DTFs. Dimensions: time, position, channel (more details see doc: HRTF format) |
| .fs | sampling rate of impulse responses |
| .pos | 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:
- SOFA API from http://sourceforge.net/projects/sofacoustics for Matlab (in e.g. thirdparty/SOFA)
- 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');
