+at the MIT Media Lab (http://sound.media.mit.edu/KEMAR.html). The diffuse-field
+equalized HRTFs are used in this plugin. filter two is the original
+SoundHack binaural filter developed by Dr. Durand Begault.;

+#X text 25 8 +binaural~;
+#X text 27 39 +binaural~ is a filter which places a sound at a specific
+position around the listener's head. It does this by using filters
+which simulate the filtering effect of the head and outer ear for sounds
+at all angles. The filters in +binaural~ are optimized for headphones
+and are only for 0 degree elevation at a 44100 sample rate.;
