- # 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.
- #
- # The SOFA conversion is available from:

- # The original data is available from:

- # It is copyrighted 1994 by MIT Media Laboratory, and provided free of charge
- # with no restrictions on use so long as the authors (above) are cited.
-
- # Sampling rate of the HRIR data (in hertz).
- rate = 44100
-
- # The SOFA file is stereo, but the original data was mono. Channels are just
- # mirrored by azimuth; so save some memory by allowing OpenAL Soft to mirror
- # them at run time.
- type = mono
-
- points = 512
-
- radius = 0.09
-
- # The MIT set has only one field with a distance of 1.4m.
- distance = 1.4
-
- # The MIT set varies the number of azimuths for each elevation to maintain
- # an average distance between them.
- azimuths = 1, 12, 24, 36, 45, 56, 60, 72, 72, 72, 72, 72, 60, 56, 45, 36, 24, 12, 1

- # Normally the dataset would be composed manually by listing all necessary
- # 'sofa' sources with the appropriate radius, elevation, azimuth (counter-
- # clockwise for SOFA files) and receiver arguments:
- #
- # [ 5, 0 ] = sofa (1.4, -40.0, 0.0 : 0) : "./mit_kemar_normal_pinna.sofa"
- # [ 5, 1 ] = sofa (1.4, -40.0, 353.6 : 0) : "./mit_kemar_normal_pinna.sofa"
- # [ 5, 2 ] = sofa (1.4, -40.0, 347.1 : 0) : "./mit_kemar_normal_pinna.sofa"
- # [ 5, 3 ] = sofa (1.4, -40.0, 340.7 : 0) : "./mit_kemar_normal_pinna.sofa"
- # ...
- #
- # If HRIR composition isn't necessary, it's easier to just use the following:
-
- [ * ] = sofa : "./mit_kemar_normal_pinna.sofa" mono
