Binaural audio in a nutshell

Generate DEF

Generates a Definition file (.DEF) used by makemhr.exe v1.20.1 or makehrtf.exe v1.18.2 to generate .MHR files compatible with OpenAL Soft and X3DAudio HRTF, respectively.
To generate a .DEF file, open the respective .bat with a text editor to find the expected file/folder structure and set it up accordingly (Usually the top .WAV/.DAT folder or .SOFA file in the same folder as the script).
Note: These scripts are intended for the listed HRIRs since it generates a template using specific configuration required by each particular HRIR.
