When listening to these sound files, it is best to use equipment with a flat frequency response, so as to avoid spectral distortion. Features that alter the signal in any way, such as spatialization features, should be turned off. And make sure that the playback amplitude is not too high and that the sounds coming from the two loudspeakers are roughly equal in loudness.
