# This is a makehrtf HRIR definition file.  It is used to define the layout

# This definition is used to transform the near-field KEMAR HRIRs provided by
# Bosun Xie <phbsxie@scut.edu.cn> of the South China University of
# Technology, Guangzhou, China; and converted from SCUT to SOFA format by
# Piotr Majdak <piotr@majdak.com> of the Acoustics Research Institute,
# Austrian Academy of Sciences.

# While the SOFA file is stereo, doubling the size of the data set will cause

# dummy head is symmetric, the same results (ignoring variations caused by
# measurement error) can be obtained using mono channel processing.
