# This is a makemhr HRIR definition file. It is used to define the layout and
|
|
# source data to be processed into an OpenAL Soft compatible HRTF.

# This definition is used to transform the SOFA packaged KEMAR HRIRs

# originally provided by Bill Gardner <billg@media.mit.edu> and Keith Martin

# <kdm@media.mit.edu> of MIT Media Laboratory.

# Normally the dataset would be composed manually by listing all necessary

# 'sofa' sources with the appropriate radius, elevation, azimuth (counter-

|
|
# [ 5, 0 ] = sofa (1.4, -40.0, 0.0 : 0) : "./mit_kemar_normal_pinna.sofa"

# If HRIR composition isn't necessary, it's easier to just use the following:
