+#X text 20 46 cw_binaural~ provide support for any hrtf database that
+can be used through the message set_hrtf_db \, which has 4 arguments
+1st arg is the path to the directory containing the hrtf database to
+use \, such than each impulse response is stored in a wave file whose
+name contains the azimuth and elevation of the hrtf in degree 2nd arg
+is a regexp telling how to decode the wav file name: the regexp MUST
+have 2 groups corresponding to the azimuth and elevation 3rd arg should
+have the values 'true' \, or 'false': it tells if the azimuth correspond
+to the first group of the regexp. if set to false \, then the elevation
+is the first group of the regexp 4th arg should have the values 'true'
+or 'false'. If set to true \, then the database is sampled using vertical-polar
+coordinates (like listen database) \, if set to false \, the database
+is sampled using interaural-polar coordinates (like cipic database).
+Those coordinate systems are represented in the figure bellow \, comming
+from the CIPIC Interface lab.;
