Binaural Simulation Usually, when you listen through headphones, the music sounds like it's being performed "in your head". For my M.Sc. I tried to simulate the sound that reaches your ears from a sound source nearby. In theory, if you calculate the signal that would reach your ears, then replay this signal through a pair of headphones, then the listener hears the sound as originating from outside their head. I gave a paper on this topic at the AES conference in Amsterdam. In the following demonstration, a rather trashy piece of music is simulated to move around your head. To hear the effect, download one of the following audio files, and listen to it through headphones. Download the demo as a .zip of a .mp3 file. (762k - best choice if you can decode it) Download part of the demo in .wav format 32kHz 16bit stereo (1.83MB!) Though the source is simulated to move around the listener's head in a clockwise direction, few people actually hear this. Typically it sounds like it either goes around the back of your head, or through your head emerging to the left and right. If it stays right in the centre of your head, you are playing the sound file in mono and should adjust your sound card or reply software settings for stereo playback. Other Binaural Demos
